Collecting Ethernet Setup Information

IP Address - An IP Address is required for TCP/IP protocol. The IP Address is the unique 32-bit number assigned to your Prestige. This address is written in dotted decimal notation (four 8-bit numbers, between 0 and 255, separated by periods), e.g., 192.168.1.1.

Record the IP Address into the worksheet as assigned by your network administrator. Please note that every machine on an internet must have a unique IP address - do not assign an arbitrary address to any machine. If you are not sure as to which IP address to assign to the Prestige, contact your LAN administrator or refer to Chapter 4 of this guide for more details.

IP Subnet Mask - This field is required for TCP/IP protocol. An IP address consists of two parts, the network ID and the host ID. The IP Subnet Mask is used to spe cify the network ID portion of the address, expressed in dotted decimal notation. The Prestige automatically calculates this mask based on the IP address that you assign. Unless you have special need for subnetting, use the default mask as calculated by the Prestige.

The table below lists some examples of IP subnet masks and the number of hosts that are allowed.

Consult your network administrator if you are unsure of this value.

2.8 European ISDN Setup Menus

Menu 2 is for you to enter the information about your ISDN line. Please note that the Prestige only accepts digits in phone number fields; please do no include ‘-‘ or spaces in these fields.

2.8.1 Switch Type

The only switch type supported in Europe is DSS-1.

2.8.2 MSN and Subaddress

Depending on your location, you may have Multiple Subscriber Number (MSN) where the telephone company gives you more than one number for your ISDN line. You can assign each number to a different port, e.g., the first number to data calls, the second to A/B adapter 1 and so on. Or the telephone company may give you only one number, but allow you to assign your own subaddresses to different ports, e.g., subaddress 1 to data calls and 2 to A/B adapter 1.

2.8.3 Incoming Call Routing

The Incoming Phone Number Matching setting governs how incoming calls are routed. If you select Multiple Subscriber Number (MSN) or Called Party Subaddress, a call (either

ISDN data or analog) is routed to the port that matches the dialed number; if no match is found, the call is dropped.

If you select Don’t Care, then all data calls are routed to the Prestige itself. Analog calls, however, are routed to either A/B adapter 1 or 2, or simply ignored, depending on the Analog

Call Routing field.

2.8.4 Global Calls

A global call is an incoming analog call where the switch did not send the dialed number. This happens most often when the call originates from an analog telephone line.

If you specify explicit matching, i.e., Incoming Phone Number Matching is either MSN or

Called Party Subaddress, then global calls are always ignored. If it is Don’t Care and Analog

2-14

Hardware Installation and Setup

Prestige 128IMH ISDN Modem/ Router/Hub

Call Routing is either A/B Adapter 1 or 2, then the Prestige uses Global Analog Call to decide how to handle global calls. If you set Global Analog Call to Accept, then global calls are routed to the port according to the Analog Call Routing setting; if you set Global Analog Call to

Ignore, then the Prestige ignores all global calls. If Analog Call Routing is Ignore to begin with, then all analog calls, including global calls, are ignored.

2.8.5 Modem Calls

The built-in modem is internally connected to A/B adapter 2. If you wish to receive modem calls, you must set the A/B Adapter 2 Accepts Modem Call field to Enable. When this field is enabled, only the modem receives the incoming analog calls routed to A/B adapter 2 according to the description above; the external device will not ring. Note that this field only controls the incoming calls; you can still place outgoing modem calls even if this field is Disable.

2.8.6 PABX Outside Line Prefix

A PABX (Private Automatic Branch eXchange) generally requires you to dial a number (a single digit in most cases) when you need an outside line. If your Prestige is connected to a PABX, enter this number in PABX Outside Line Prefix, otherwise, leave it blank.

Please note that the PABX prefix is for calls initiated by the Prestige only. If you place a call from a device on either A/B adapter, you must dial the prefix by hand.

3.2 TCP/IP Parameters

3.2.1 IP Address and Subnet Mask

Similar to the houses on a street that share a common street name, the machines on a LAN share one common network number, also.

Where you obtain your network number depends on your particular situation. If the ISP or your network administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask.

If the ISP did not explicitly give you an IP network number, then most likely you have a single user account and the ISP will assign you a dynamic IP address when the connection is established.

If this is the case, it is recommended that you select a network number from 192.168.0.0 to

192.168.255.0 (ignoring the trailing zero) and you must enable the Single User Account feature of the Prestige. The Internet Assigned Number Authority (IANA) reserved this block of addresses specifically for private use; please do not use any other number unless you are told otherwise.

Let’s say you sele ct 192.168.1.0 as the network number; which covers 254 individual addresses, from 192.168.1.1 to 192.168.1.254 (zero and 255 are reserved). In other words, the first 3 numbers specify the network number while the last number identifies an individual workstation on that network.

Once you have decided on the network number, pick an IP address that is easy to remember, e.g.,

192.168.1.1, for your Prestige.

The subnet mask specifies the network number portion of an IP address. Your Prestige will compute the subnet mask automatically based on the IP address that you entered. You don’t need to change the subnet mask computed by the Prestige unless you are instructed to do otherwise.

3.2.2 RIP Setup

RIP (Routing Information Protocol) allows a router to exchange routing information with other routers. The RIP Direction field controls the sending and receiving of RIP packets. When set to both, the Prestige will broadcast its routing table periodically and incorporate the RIP information

3-2 Internet Access

Prestige 128IMH ISDN Modem/ Router/Hub that it receives; when set to none, it will not send any RIP packets and will ignore any RIP packets received.

The Version field controls the format and the broadcasting method of the RIP packets that the

Prestige sends (it recognizes both formats when receiving). RIP-1 is universally supported; but

RIP-2 carries more information. RIP -1 is probably adequate for most networks, unless you have a unusual network topology.

Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the difference being that RIP-

2B uses subnet broadcasting while RIP-2M uses multicasting. Multicasting can reduce the load on non-router machines since they generally do not listen to the RIP multicast address and so will not receive the RIP packets. However, if one router uses multicasting, then all routers on your network must use multicasting, also.

By default, RIP direction is set to Both and the Version set to RIP-1.

3.2.3 DHCP Configuration

DHCP (Dynamic Host Configuration Protocol) allows the individual clients (workstations) to obtain the TCP/IP configuration at start-up from a centralized DHCP server. The Prestige has built-in DHCP server capability, enabled by default, which means it can assign IP addresses, an

IP default gateway and DNS servers to Windows 95, Windows NT and other systems that support the DHCP client.

IP Pool Setup

The Prestige is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to

192.168.1.64. This configuration leaves 31 IP addresses (excluding the Prestige itself) in the lower range for other server machines, e.g., server for mail, FTP, telnet, web, etc., that you may have.

DNS Server Address

DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and vice versa, e.g., the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely important because without it, a user must know the IP address of a machine before s/he can access

Internet Access 3-3

Prestige 128IMH ISDN Modem/ Router/Hub it. The DNS server addresses that you enter in the DHCP setup are passed to the client machines along with the assigned IP address and subnet mask.

There are two ways that an ISP disseminates the DNS server addresses. The first is for an ISP to tell a customer the DNS server addresses, usually in the form of an information sheet, when s/he signs up. If your ISP does give you the DNS server addresses, enter them in the DNS Server fields in DHCP Setup.

Some ISP’s choose to pass the DNS servers using the DNS server extensions of PPP IPCP (IP

Control Protocol) after the connection is up. If your ISP did not give you explicit DNS servers, chances are the DNS servers are conveyed through IPCP negotiation. The Prestige supports the

IPCP DNS server extensions through the DNS proxy feature.

If the Primary and Secondary DNS Server fields in DHCP Setup are not specified, i.e., left as

0.0.0.0, the Prestige tells the DHCP clients that it itself is the DNS server. When a workstation sends a DNS query to the Prestige, the Prestige forwards the query to the real DNS server learned through IPCP and relays the response back to the workstation.

Please note that DNS proxy works only when the ISP uses the IPCP DNS server extensions. It does not mean you can leave the DNS servers out of the DHCP setup under all circumstances. If your ISP gives you explicit DNS servers, make sure that you enter their IP addresses in the

DHCP Setup menu. This way, the Prestige can pass the DNS servers to the workstations and the workstations can query the DNS server directly without the Prestige’s intervention.

3.5 Single User Account

Typically, if there are multiple users on the LAN wanting to concurrently access the Internet, you will have to lease a block of legal, or globally unique, IP addresses from the ISP.

The Single User Account (SUA) feature allows you to have the same benefits as having multiple legal addresses, but only pay for one IP address, thus saving significantly on the subscription fees.

(Check with your ISP before you enable this feature).

The Single User Account feature may also be used on connections to remote networks other than the ISP. For example, this feature can be used to simplify the allocation of IP addresses when connecting branch offices to the corporate network.

Internet Access 3-11

Prestige 128IMH ISDN Modem/ Router/Hub

The IP address for the SUA can be either fixed or dynamically assigned when a call is connected.

In addition, you can designate servers, e.g., a web server and a telnet server, on your local network and make them accessible to the outside world.

If you do not define any server, SUA offers the additional benefit of firewall protection. If no server is defined, all incoming inquiries will be filtered out by your Prestige and thus preventing intruders from probing your network.

Your Prestige accomplishes this address sharing by translating the internal LAN IP addresses to a single address that is globally unique on the Internet. For more information on IP address translation, refer to RFC 1631, The IP Network Address Translator (NAT).

3.5.1 Advantages of SUA

In summary: l SUA is a cost-effective solution for small offices with less than 20 hosts to access the

Internet or other remote TCP/IP networks. l SUA supports servers to be accessible to the outside world. l SUA can provide firewall protection if you do not specify a server. All incoming inquiries will be filtered out by your Prestige. l UDP and TCP packets can be routed. In addition, partial ICMP, including echo and trace route, is supported.

3.6 Configuring Backup ISP Accounts

If you have more than one ISP account, you can configure the secondary ISP as a backup. You can switch to the backup ISP in the event that the primary ISP is out of service. The SUA feature can be enabled for all these accounts.

3.6.1 Configure a Backup ISP

To configure a backup ISP Account, follow these steps:

Step 1.

Configure your primary ISP using Menu 4, as described earlier in this chapter.

Step 2.

Enter Menu 11, then select an unused remote node.

Step 3.

In Menu 11.1, choose a name for your backup ISP account, then set the Active field to

No, and enter your outgoing login name, password, and phone number(s). The Remote

IP Address field should be set to 1.1.1.1.

Step 4.

In Menu 11.3, set the remote node's subnet mask to 0.0.0.0, and set RIP to None .

Step 5.

Save the new configuration.

Please note that the remote IP address of 1.1.1.1 is only a placeholder to avoid conflicting with that of the primary ISP, which is implicitly set at 0.0.0.0. When the backup ISP is activated, the remote IP address of 1.1.1.1 combined with the subnet mask of 0.0.0.0 creates a default route that is equivalent to the one derived form the primary ISP.

3.6.2 To Switch ISP

Follow these steps when you need to switch from your primary ISP to a backup ISP:

Step 1.

Enter Menu 11 and select your Primary ISP.

Step 2.

In Menu 11.1, set the Active field to No.

Chapter 4 Remote Node Configuration

A remote node is required for placing calls to a remote gateway. A remote node represents both the remote gateway and the network behind it across a WAN connection. Note that when you use

Menu 4 to set up Internet access, you are actually configuring one of the remote nodes. Once a remote node is configured correctly, traffic to the remote network will trigger your Prestige to make a call automatically, i.e., Dial On Demand.

In this chapter, we will discuss the parameters that are protocol independent. The protocoldependent configuration will be covered in subsequent chapters. For TCP/IP, see Chapter 5, for

IPX, see Chapter 6 and for Bridging, see Chapter 7.

4.1.2 Nailed-up Connection

A nailed-up connection is a dial-up line where the connection is always up regardless of traffic demand. The Prestige does two things when you specify a nailed-up connection. The first is that idle timeout is disabled. The second is that the Prestige will try to bring up the connection at power-on and whenever the connection is down.

A nailed-up connection can be very expensive for obvious reasons. Please do not specify a nailedup connection unless your telephone company offers flat-rate service or you need a constant connection and the cost is of no concern.

4.1.3 Outgoing Authentication Protocol

Generally speaking, you should employ the strongest authentication protocol possible, for obvious reasons. However, some vendor’s implementation includes specific authentication protocol in the user profile. It will disconnect if the negotiated protocol is different from that in the user profile, even when the negotiated protocol is stronger than specified. If you encounter the case where the

4-6 Remote Node Configuration

Prestige 128IMH ISDN Modem/ Router/Hub peer disconnects right after a successful authentication, please make sure that you specify the correct authentication protocol when connecting to such an implementation.

4.1.4 PPP Multilink

The Prestige uses the PPP Multilink Protocol (PPP/MP ) to bundle multiple links in a single connection to boost the effective throughput between two nodes. The bundle works best when the member links are of the same type of call (e.g., modem vs. ISDN) and at approximately the same speed.

Due to the fragmentation/reconstruction overhead associated with MP, you may not get a linear increase in throughput when a link is added.

The number of links in an MP bundle can be statically configured, or dynamically determined at runtime, as explained in the following section.

4.1.5 Bandwidth on Demand

The Bandwidth on Demand (BOD) feature adds or subtracts links dynamically according to traffic demand. After the initial call, the Prestige uses BAP (Bandwidth Allocation Protocol) to ask the peer for additional telephone number if BACP (Bandwidth Allocation Control Protocol) is negotiated. Otherwise, the Prestige uses the statically configured (primary and secondary) telephone numbers of the remote node.

The configuration of bandwidth on demand focuses on the Base Transmission Rate (BTR) and the

Maximum Transmission Rate (MTR). The relationship between BTR and MTR are shown below:

BTR & MTR Setting

BTR = 64, MTR = 64

BTR = 64, MTR = 128

BTR = 128, MTR = 128

No. of channel(s) used

Max No. of channel(s) used

Bandwidth on demand

Off

Remote Node Configuration 4-7

Prestige 128IMH ISDN Modem/ Router/Hub

When bandwidth on demand is enabled, a second channel will be brought up if traffic on the initial channel is higher than the high Target Utility number for longer than the specified Add

Persist value. Similarly, the second channel will be dropped if the traffic level falls below the low

Target Utility number for longer than the Subtract Persist value.

The Target Utility specifies the line utilization range at which you want the Prestige to add or subtract bandwidth. The range is 30 to 64 kbps (kilobits per second). The parameters are separated by a ‘-’. For example, ‘30-60’ means the add threshold is 30 kbps and subtract threshold is 60 kbps. The Prestige performs bandwidth on demand only if it initiates the call. Addition and subtraction are based on the value set in the BOD Calculation field. If this field is set to

Transmit or Receive, then traffic in either direction will be inclu ded to determine if a link should be added or dropped. Transmit will only use outgoing traffic to make this determination and Receive will only use incoming traffic to make this determination.

If, after making the call to bring up a second channel, the second channel does not succeed in joining the Multilink Protocol bundle (because the remote device does not recognize the second call as coming from the same device), the Prestige will hang up the second call and continue with the first channel alone.

The BOD configuration is through Menu 11.2 - Remote Node PPP Options.

Some implementations, especially the UNIX derivatives, require the ISDN link to have a separate IP network number from the LAN and each end must have a unique address within the WAN network number. If this is the case, enter the IP address assigned to the ISDN port of your Prestige.

Note that this is the address assigned to your local Prestige, not the remote router.

Set this field to Yes to enable the Single User Account feature for your Prestige. Use the space bar to toggle between Yes and No. See Chapter 3 - Internet Access Application for more information on the Single User Account feature.

The metric represents the “cost” of transmission for routing purposes. IP routing uses hop count as the measurement of cost, with a minimum of 1 for directly connected networks.

Enter a number that approximates the cost for this link. The number need not be precise, but it must be between 1 and 15.

In practice, 2 or 3 is usually a good number.

This parameter determines if the Prestige will include the route to this remote node in its RIP broadcasts. If set to Yes, this route is kept private and not included in RIP broadcast. If No, the route to this remote node will be propagated to other hosts through RIP broadcasts.

5.1.2 Static Route Setup

Static routes tell the Prestige routing information that it cannot learn automatically through other means. This can arise in cases where RIP is disabled on the LAN or a remote network is beyond the one that is directly connected to a remote node.

Each remote node specifies only the network to which the gateway is directly connected, and the

Router 1

Router 2

Prestige

Prestige has no knowledge of the networks beyond. For instance, the Prestige knows about network N2 in the following diagram through remote node R. Howeve r, the Prestigeis unable to route a packet to network N3 because it doesn’t know that there is a route through remote node R.

The static routes are for you to tell the Prestige about the networks beyond the remote nodes.

Chapter 6 IPX Configuration

This chapter shows you how to configure the IPX parameters of the Prestige.

6.1 IPX Network Environment

Novell bundles the protocol stack, the server software and routing functionality in their NetWare server products. So a NetWare server is not only a file or print server, it is also a router.

6.1.1 Network and Node Number

Every IPX machine has a network number and a node number, together they form the complete address of the machine. The IPX network number is a 32-bit quantity and is usually expressed in

8 hexadecimal digits, e.g., 0893A8CF. The host number is a 48-bit quantity and usually is taken from the MAC (Media Access Control) address of the Ethernet hardware, so you don’t have to explicitly configure the node number.

An IPX client obtains its network number from a server that has the network numbers statically configured. If there are multiple servers on a network, only one server need to have the network numbers configured, and all other stations (clients and servers) can obtain the network numbers from it. The server with configured network numbers is called a seed router.

If you have a NetWare server on the same LAN as the Prestige, we recommend that you set up a

NetWare server as a seed router. Even though the Prestige is capable as a seed router, a NetWare server offers a much more extensive facility for network management.

IPX Configuration 6-1

Prestige 128IMH ISDN Modem/ Router/Hub

6.1.2 Frame Types

IPX can run on top of four different frame types on the Ethernet. These frame types are 802.2,

802.3, Ethernet II (DIX), and SNAP (Sub-Network Access Protocol). Each frame type is a separate logical network, even though they exist on one physical cable.

Although there are four frame types available on the Ethernet, you should configure as few frame types as possible on your NetWare server and use automatic frame detection on the clients to simplify management and to reduce network overhead.

6.1.3 External Network Number

Each of the four logical networks (based on frame type) has its own external network number.

6.1.4 Internal Network Number

In addition to the external network numbers, each NetWare server has its own internal network number that is a virtual network to which the server is attached. It is important to remember that every network number must be unique for that entire internetwork, either internal or external.

If your Prestige is on a LAN with a seed router, you do not need to configure the LAN network numbers. Your Prestige will learn the network number from the seed router and add the routes to its routing table.

6-4 IPX Configuration

Prestige 128IMH ISDN Modem/ Router/Hub

6.2.2 Prestige on LAN without Server

Each IPX network must have a seed router. If you only have NetWare clients on your network, then you must configure the Prestige as a seed router and set up unique network numbers for each frame type enabled using the Ethernet Setup Menu.

6.3 IPX Spoofing

Your Prestige comes with several pre-defined call filters designed to prevent certain IPX packets from triggering a call to a remote node.

The built-in call filters are defined as follows: l Block periodical RIP (Routing Information Protocol) and SAP (Service Advertising

Protocol) response messages. l Block NetWare serialization packets. l Allow SAP and RIP inquiry packets.

Chapter 7 Bridging Setup

This chapter shows you how to configure the bridging parameters of your Prestige.

7.1 Bridging in General

Bridging bases the forwarding decision on the MAC (Media Access Control), or hardware, address, while routing does it on the network layer (IP or IPX) address. Bridging allows the

Prestige to transport packets of network layer protocols that the Prestige does not route, e.g.,

SNA, from one network to another. The caveat is that, compared to routing, bridging generates more traffic for the same network layer protocol, and it also demands more CPU cycles and memory.

For efficiency reason, do not turn on bridging unless you need to support protocols other than IP and IPX on your network. For IP and IPX, enable the respective routing if you need it; do not bridge what the Prestige can route.

7.2 Bridge Ethernet Setup

Basically, all non-local packets are bridged to the WAN; however, your Prestige applies special handling for certain IPX packets to reduce the number of calls, depending on the setting of the

Handle IPX field.

The period of time that your Prestige will do this is linked to the Ethernet

Address Timeout parameter in each remote node (see Remote Node

Configuration). When a remote Ethernet address is aged out, there is no need to maintain its connection to the IPX server.

If there are both clients and servers on the LAN, and the local clients will access the remote servers, set this field to Server but turn on the Dial-On-Broadcast parameter in Menu 11.3 to allow the client queries to trigger calls.

Prestige 128IMH ISDN Modem/ Router/Hub

Chapter 8 Dial-in Server Configuration

You can configure your Prestige to receive calls from remote dial-in users, e.g., telecommuters, as well as remote nodes. There are several differences between dial-in users and remote nodes, as summarized in the table below.

Table 8-1 Remote Dial-in Users/Remote Nodes Comparison Chart

Remote Dial-in Users Remote Nodes

Your Prestige will only answer calls from remote dial-in users; it will not make call to them.

Your Prestige can make calls to and receive calls from the remote node.

All remote dial-in users share one common set of parameters, as defined in the Default Dial In Setup

(Menu 13).

Each remote node can have its own set of parameters such as Bandwidth On Demand,

Protocol, Security, etc.

This chapter discusses how to setup default dial-in parameters for both remote node and remote dial-in users. The following sections give two examples of how your Prestige can be configured as a dial-in server.

Due to memory constraints, your Prestige can only store a finite number of users locally. If there are more remote dial-in users than what Prestige can support locally, you can use an external RADIUS server to provide authentication service. For details on using a RADIUS server, see the Using RADIUS Authentication section in Chapter 11 - System Security.

Dial-I n Server Configuration 8-1

Prestige 128IMH ISDN Modem/ Router/Hub

8.1 Remote Access Server

Telecommuting enables people to work at remote sites and yet still have access to the resources in the business office. Typically, a telecommuter will use a client workstation with

TCP/IP and dial-out capabilities, e.g., a Windows PC or a Macintosh. For telecommuters to call in to your Prestige, you need to configure a dial-in user profile for each telecommuter.

Additionally, you need to configure the Default Dial-In Setup to set the operational parameters for all dial-in users.

An example of remote access server for telecommuters is shown in .

Option

Idle Timeout

Enter the idle time (in seconds). This time-out determines how long the dial-in user can be idle before your Prestige disconnects the call when the Prestige is calling back.

Default=300 seconds

Idle time is defined as the period of time where there is no data traffic between the dial-in user and your Prestige. The default is 300 seconds (5 minutes).

ENTER to Confirm…] to save your configuration, or press [Esc] at any time to cancel.

8.4.1 CLID Authentication

CLID (Calling Line IDentification) authentication affords you the security of limiting a user to only initiate connections from a fixed location. The Prestige uses the caller ID sent by the switch to match against the CLIDs in the database. Please note that for CLID authentication to work on the Prestige, your telephone company must support caller ID. You must also include the AT command in the [ initAT

] string in Menu 2 to enable caller ID detection on the modem.

8.4.2 Callback

Callback serves two purposes. One is security. When set to callback to a fixed number, an intruder will not gain access to your network even if he/she stole the password from your user, because the Prestige always calls back to the pre-configured number.

The other is ease of accounting. For instance, your company pays for the connection charges for telecommuting employees and you use your Prestige as the dial in server. When you turn on the callback option for the dial-in users, all usage is charged to the company instead of the

Dial-I n Server Configuration 8-11

Prestige 128IMH ISDN Modem/ Router/Hub employees, and your accounting department can avoid the hassles of accountability and reimbursement.

8.5 Multiple Servers behind SUA

If you wish, you can make inside servers for different services, e.g., web or FTP, visible to the outside users, even though SUA makes your whole inside network appear as a single machine to the outside world. A service is identified by the port number, e.g., web service is on port

80 and FTP on port 21.

As an example, if you have a web server at 192.168.1.2 and an FTP server 192.168.1.3, then you need to specify for port 80 (web) the server at IP address 192.168.1.2 and for port 21

(FTP) another at IP address 192.168.1.3.

Please note that a server can support more than one service, e.g., a server can provide both

FTP and DNS service, while another provides only web service. Also, since you need to specify the IP address of a server in the Prestige, a server must have a fixed IP address and not be a DHCP client whose IP address potentially changes each time it is powered on.

In addition to the servers for specific services, SUA supports a default server. A service request that does not have a server explicitly designated for it is forwarded to the default server. If the default server is not defined, the service request is simply discarded.

To make a server visible to the outside world, specify the port number of the service and the inside IP address of the server in Menu 15, Multiple Server Configuration.

8.5.1 Configuring a Server behind SUA

Chapter 9 Advanced Phone Services

The Prestige 128IMH supports a comprehensive set of advanced calling features known as

Supplemental Services. These features include:

•

Call Waiting

•

Three Way Calling (conference)

•

Call Transfer

•

Call Forwarding

9.1 Getting Started

9.1.1 Things you need to know before you start using Supplemental

Services.

♦

Additional Call Offering (ACO) is required on your ISDN line in order to use the Call

Waiting feature. Flexible Calling is required on your ISDN line in order to use the Three-

Way-Calling or Call Transfer features. You need to check with your telephone company to confirm if these services are available to you and if so, are there any additional charges for them.

♦

In some cases, your telephone company may only enable these features on your first directory

(phone) number. In this case, you may want to request that the features be enabled on your second directory number as well.

Advanced Phone Services 9-1

Prestige 128IMH ISDN Modem/ Router/Hub

9.2 Setting Up Supplemental Phone Service

All Supplemental Phone Services are enabled by default except for Call Waiting, which is disabled by default but can be enabled in Menu 2.1- ISDN Advanced Setup. The Calling Line

Indication, or Caller ID, also in this menu decides whether the other party can see your number when you call. If set to Enable (default), the Prestige sends the caller ID and the party you call can see your number, otherwise, the caller ID is blocked.

9.3 The Flash Key

Flashing means to press the hook for a short period of time (a few hundred milliseconds) before releasing it. On newer telephones, there should be a “flash” key (button) that generates the signal electronically. If the flash key is not available, you can tap (press and immediately release) the hook by hand to achieve the same effect. However, using the flash key is preferred since the timing is much more precise. With manually tapping, if the duration is too long, it may be interpreted as hanging up by the Prestige.

9.4 Call Waiting

ISDN Call Waiting allows you to place a call on hold while you answer another incoming call on the same telephone (directory) number.

By default call waiting is disabled on both telephone ports, but can be enabled on either port from

Menu 2.1.

9.4.1 How to use call waiting

The Call Waiting feature on your ISDN line works in exactly the same way as it does on a regular analog line (which almost everyone is familiar with). To put the current call on hold and answer the incoming call, press the flash key after hearing a call waiting indicator tone.

Dropping current call to switch to incoming/holding call.

9-2 Advanced Phone Services

Prestige 128IMH ISDN Modem/ Router/Hub

After hearing a Call Waiting indicator tone, simply hang up the telephone and wait for the telephone to ring before answering the incoming/holding call.

Notes: An incoming caller receives a busy signal if

♦

You have two calls active (one active and one on hold, or both active using Three Way

Calling) already.

♦

You are dialing a number on the B-Channel the incoming caller is attempting to reach, but have not yet established a connection.

9.5 Three way calling

The Three Way Call feature allows you to add a third party to an existing call. This service must be subscribed from your telephone company.

9.5.1 How To Use Three Way Calling

If you wish to call someone and conference him/her in with an existing call:

♦

Press the flash key to put the existing call on hold and receive a dial tone.

♦

Dial the third party’s telephone number.

♦

When you are ready to conference the calls together, press the flash key again to establish a

Three Way Conference Call.

Note: If you wish to cancel your attempt to establish the conference call because the third party’s line in busy or if they don't answer, simply hang-up the telephone and pick it back up after it starts ringing to return to the first caller.

To drop the last call added to the three-way-call:

Simply press the flash key. The last call that was added to the conference is dropped.

To drop yourself from the conference call:

Advanced Phone Services 9-3

Prestige 128IMH ISDN Modem/ Router/Hub

If you hang up your telephone during a three-way-call and the two other callers remain on the line, the ISDN network will do an implicit transfer to directly connect the two remaining callers together.

9.6 Call Transfer

Call Transfer allows you to transfer an active call to a third party. This service must be subscribed from your telephone company.

9.6.1 How To Use Call Transfer

Transferring an active call to a third party:

♦

Once you have an active call (Caller A), press the flash key to put Caller A on hold and receive a dial tone.

♦

Dial the third party’s telephone number (Caller B).

♦

When you are ready to conference the two calls together, press the flash key to establish a

Three-Way-Conference call.

♦

Hang up the telephone. The ISDN network does an implicit transfer to directly connect Caller

A with Caller B.

9.6.2 To Do A Blind Transfer:

♦

Once you have an active call (Caller A), press the flash key to put the existing call on hold and receive a dial tone.

♦

Dial the third party’s telephone number (Caller B).

♦

Before Caller B picks up the call, you can transfer the call by pressing the flash key. The call is automatically transferred.

9.7 Call Forwarding

Call forwarding means the switch will ring another number at a place where you will be when someone dials your directory number.

There are two methods to activate call forwarding. The first is exactly the same as on an analog line, i.e., you pick up the handset and dial the access code assigned by your telephone company and the number that you want the calls forwarded.

The second is with the “phone flash” commands where you pick up the handset and press the flash key before dialing the following:

Command

*20*forward-number#

*21*forward-number#

*22*forward-number#

#20#

#21#

Meaning

Activate CFB (Call Forwarding Busy)

Activate CFU (Call Forwarding Unconditional)

Activate CFNR (Call Forwarding No Reply)

Deactivate CFB

Chapter 10 Filter Configuration

10.1 About Filtering

Your Prestige uses filters to decide whether or not to allow passage of a data packet and/or to make a call. There are two types of filters: data filters and call filters.

Data filters screen the data to determine if the packet should be allowed to pass. Data filters are further divided into incoming and outgoing filters, depending on the direction of the packet relative to a port. Call filters are used to determine if a packet should be allowed to trigger a call.

Outgoing packets must pass through the data filters before they encounter the call filters. Call filters are divided into two groups, the built-in call filters and user-defined call filters. Your

Prestige has built-in call filters that prevent administrative, e.g., RIP and SAP (Service

Advertising Protocol), packets from triggering calls. These filters are always enabled and not accessible to you. Your Prestige applies the built-in filters first and then the user-defined call filters, if applicable, as illustrated in the figure below, Figure 10-1 Outgoing Packet Filtering

Process.

For incoming packets, your Prestige applies data filters only. Packets are processed depending upon whether a match is found. The following sections describe how to configure filter sets.

The Filter Structure of the Prestige

A filter set consists of one or more filter rules. Usually, you would group related rules, e.g., all the rules for NetBIOS, into a single set and give it a descriptive name. The Prestige allows you to configure up to twelve filter sets with six rules in each set, for a total of 72 filter rules in the system.

You can apply up to four filter sets to a particular port to block multiple types of packets. With each filter set having up to six rules, you can have a maximum of 24 rules active for a single port.

10.3 Configuring a Filter Rule

To configure a filter rule, enter its number in Menu 21.1 - Filter Rules Summary and press Enter to open Menu 21.1.1 for the rule.

There are three types of filter rules: TCP/IP, IPX and Generic. Depending on the type of rule, the parameters below the type will be different. Use the space bar to select the type of rule that you wish to create in the Filter Type field and press Enter to open the respective menu.

The network layer (TCP/IP and IPX) filters are collectively called protocol filters. When

NAT/SUA (Network Address Translation/Single User Account) is enabled, the inside IP address and port number are replaced on a connection-by-connection basis, which makes it impossible to know the exact address and port on the wire. Therefore, the Prestige applies the protocol filters to the “native” IP address and port number before NAT/SUA for outgoing packets and after

NAT/SUA for incoming packets. On the other hand, the generic, or device, filters are applied to the raw packets that appear on the wire.

To speed up filtering, all rules in a filter set must be of the same class, i.e., protocol filters or generic filters. The class of a filter set is determined by the first rule that you create. When applying the filter sets to a port, separate menu fields are provided for protocol and device filter sets. If you include a protocol filter set in a device filters field or vice versa, the Prestige will warn you and will not allow you to save.

10.3.1 TCP/IP Filter Rule

This section shows you how to configure a TCP/IP filter rule. TCP/IP rules allow you to base the rule on the fields in the IP and the upper layer protocol, e.g., UDP and TCP, headers.

To configure a TCP/IP rules, select TCP/IP Filter Rule from the Filter Type field and press Enter to open Menu 21.1.1 - TCP/IP Filter Rule, as shown below.

10.3.2 Generic Filter Rule

This section shows you how to configure a generic filter rule. The purpose of generic rules is to allow you to filter non-IP/IPX packets. For IP and IPX packets, it is generally easier to use the IP and IPX rules directly.

For generic rules, the Prestige treats a packet as a byte stream as opposed to an IP or IPX packet.

You specify the portion of the packet to check with the Offset (from 0) and the Length fields, both in bytes. The Prestige applies the Mask (bit-wise ANDing) to the data portion before comparing the result against the Value to determine a match. The Mask and Value are specified in hexadecimal numbers. Note that it takes two hexadecimal digits to represent a byte, so if the length is 4, the value in either field will take 8 digits, e.g.,

FFFFFFFF

To configure a generic rule, select Generic Filter Rule in the Filter Type field and press Enter to open Menu 21.1.2 - Generic Filter Rule, as shown below.

12.2 Using RADIUS Authentication

Your Prestige has a built-in dial-up user list; however, the number of users that can be stored locally is limited due to memory constraints. If you have more users than what the Prestige can store locally, use an external RADIUS (Remote Authentication Dial-In User Service) server that provides authentication service for unlimited number of users.

12.2.1 Installing a RADIUS Server

To use RADIUS authentication, you need to have a UNIX or Windows NT machine on your network as the RADIUS server, as well as the RADIUS software itself.

You can obtain the RADIUS server software, along with documentation, at

http://www.livingston.com/Tech/FTP/pub-le-radius.shtml

ftp://ftp.livingston.com/pub/le/radius

Follow the included instructions to install the software on your server.

After you install the server software, you will need to edit the dictionary

file in the RADIUS configuration directory (usually

/etc/raddb

). Using any text editor, add the following lines to the dictionary

file:

# Zyxel proprietary attributes

ATTRIBUTE Zyxel-Callback-Option 192 integer

VALUE Zyxel-Callback-Option None 0

VALUE Zyxel-Callback-Option Optional 1

VALUE Zyxel-Callback-Option Mandatory 2

# Callback phone number source

ATTRIBUTE Zyxel-Callback-Phone-Source 193 integer

VALUE Zyxel-Callback-Phone-Source Preconfigured 0

VALUE Zyxel-Callback-Phone-Source User 1

These changes add the support for CLID authentication, as described in the section below.

file in the RADIUS server’s

/etc/raddb

directory, as shown in the following example:

# Client Name Key

#-------------------------

192.168.1.1 1234

After you configure a RADIUS server, your Prestige will use it to authenticate all users that it can not find in its internal dial-up user list (see Menu 14)

12.2.4 Adding Users to the RADIUS Database

To add a user to the RADIUS database, edit the users

file in the RADIUS server’s

/etc/raddb directory, and add a line similar to the following:

Joeuser Password = “joepassword”

12-6 System Security

Prestige 128IMH ISDN Modem/ Router/Hub

12.2.5 Using RADIUS Authentication for CLID

To use RADIUS for CLID authentication, create a user record in the users

file where the user name (the first field) is the telephone number, and the password (the second field) is always

Zyxel-CLID

(case-sensitive). The regular user name is put in a User-Name field. The following is an example of a CLID user record:

5551212 Password = “Zyxel-CLID”

User-Name = ”joeuser”

Zyxel-Callback-Option = Mandatory

Zyxel-Callback-Phone-Source = Preconfigured

Dialback-No = “5551212”

Note that if CLID is turned off in your Prestige, you need to have a separate user record for joeuser so the regular user name/password mechanism still works.

Chapter 13 Telnet Configuration and Capabilities

13.1 About Telnet Configuration

Before the Prestige is properly setup for TCP/IP, the only option for configuring it is through the console port. Once your Prestige is configured, you can use telnet to configure it remotely as shown below.

Figure 13-1 Telnet Configuration on a TCP/IP Network

If your Prestige is configured for IPX but not IP routing in Menu 1, telnet is still available provided you assign the Prestige a correct IP address and subnet mask. When IP routing is disabled, the Prestige can still function as a host.

Telnet Configuration 13-1

Prestige 128IMH ISDN Modem/ Router/Hub

13.2 Telnet Under SUA

When Single User Account (SUA) is enabled and an inside server is specified, telnet connections from the outside will be forwarded to the inside server. So to configure the Prestige via telnet from the outside, you must first telnet to the inside server, and then telnet from the server to the

Prestige using its inside LAN IP address. If no insider server is specified, telnet to the SUA’s IP address will connect to the Prestige directly.

13.3 Telnet Capabilities

13.3.1 Single Administrator

To prevent confusion and discrepancy on the configuration, your Prestige only allows one administrator to log in at any time. Your Prestige also gives priority to the console port over telnet. If you have already connected to your Prestige via telnet, you will be logged out if another user logs in to the Prestige via the console port.

13.3.2 System Timeout

There is a system timeout of 5 minutes (300 seconds) for either the console port or telnet. Your

Prestige will automatically log you out if you do nothing in this timeout period, except when it is continuously updating the status in Menu 24.1.

14.6.3 TFTP Transfer

In addition to the direct console port connection, the Prestige supports the up/downloading of the firmware and the configuration file using TFTP (Trivial File Transfer Protocol) over LAN. Even though TFTP should work over WAN as well, it is not recommended because of the potential data corruption problem.

To use TFTP, your workstatio n must have both telnet and TFTP clients. To transfer the firmware and the configuration file, follow the procedure below:

Step 1. Use telnet from your workstation to connect to the Prestige and log in. Because TFTP does not have any security check, the Prestige records the IP address of the telnet client and accepts TFTP requests only from this address.

System Maintenance 14-17

Prestige 128IMH ISDN Modem/ Router/Hub

Step 2. Put the SMT in command interpreter (CI) mode by entering 8 in Menu 24 – System

Maintenance.

Step 3. Enter command “sys stdio 0” to disable SMT timeout, so the TFTP transfer will not be interrupted.

Step 4. Launch TFTP client on your workstation and connect to the Prestige. Set the transfer mode to binary before starting data transfer.

Step 5. Use the TFTP client to transfer files between the Prestige and the workstation. The file name for the firmware is “ ras

” and for the configuration file, “rom-0” (romzero, not capital o).

If you upload the firmware to the Prestige, it will reboot automatically when the file transfer is completed.

Note that the telnet connection must be active and the SMT in CI mode before and during the

TFTP transfer. For details on TFTP commands, please consult the documentation of your TFTP client program. For UNIX, use “get” to transfer from the Prestige to the workstation, “put” the other way around, and “binary” to set binary transfer mode.

14.6.4 Boot module commands

Prestige boot module commands are shown below. For ATBAx, x denotes the number preceeding the colon to give the baud rate following the colon in the list of numbers that follows; e.g.

ATBA3 will give a baud of 9.6 kbps. ATSE displays the seed that is used to generate a password to turn on the debug flag in the firmware. The ATSH command shows product related information such as boot module version, vendor name, product model, RAS code revision, ISDN code revision, etc.

14.8 Call Control

The Prestige provides four call control functions: call control parameters, blacklist, budget management andcall history..

Call control parameters allows you to set a dial out time limit, the number of times a number should be called before it is added to the blacklist and the interim between calls.

The budget management function allows you to set a limit on the total outgoing call time of the

Prestige over a period of time. When the total outgoing call time exceeds the limit, the current call will be dropped and any future outgoing calls will be blocked.

The blacklist function prevents the Prestige from re-dialing to an unreachable phone number. It is a list of phone numbers, up to a maximum of 14, to which the Prestige will not make an outgoing call. If the Prestige tries to dial to a phone number and fails a certain number of times

14-20 System Maintenance

Prestige 128IMH ISDN Modem/ Router/Hub

(configurable in Menu 24.9.1), then the phone number is put in the blacklist. You will have to enable the number manually before the Prestige will dial that number again.
