WAN IP Address field.
P-2024 Support Notes
Using Dynamic DNS (DDNS)
1.
What is DDNS?
A DNS (Domain Name Service) server stores the mappings of IP address and domain names. For example, when users enters a web site address (the domain name), the DNS server automatically maps the web site address to a public IP address and redirects the request to the intended web server.
Without DNS, users have to enter the IP address of the web server in order to access the web sites. This is very inconvenient and not user-friendly as users have to remember the IP addresses of the web sites.
12
All contents copyright (c) 2006 ZyXEL Communications Corporation.
P-2024 Support Notes
However, if the web server is located behind the P-2024 which is using a dynamic WAN IP address, a fixed mapping cannot be stored in the DNS server database since the WAN IP address changes. Thus Dynamic DNS
(DDNS) is used to solve this problem. For example, if you have hosted a web site (say www.zyxel.com) on a server behind the P-2024 which is assigned a dynamic WAN IP address from the ISP, users can still access the web site from the WAN when you have set up the DDNS settings. With DDNS, users can always access a web site regardless of the WAN IP address on the P-2024.
When the ISP assigns the P-2024 a new WAN IP address, the P-2024 sends this information to the DDNS server which updates the IP-to-DNS mapping. Once the mapping is updated, outside users can still access the web site hosted on an internal server behind the P-2024.
You must register an account with a DDNS service provider. The DDNS server saves the password-protected e-mail address with the IP addresses and host names. Queries are serviced based on the e-mail addresses. Thus you must set the same e-mail address you used for DDNS in the P-2024 SMT menu 1.
Currently, the P-2024 supports WWW.DYNDNS.ORG
for the DDNS service. The following describes the setup procedure.
•
•
Register an access with WWW.DYNDNS.ORG
DDNS service provider. You will be provided with a hostname for the internal server and a password for the IP address update on the DDNS server.
Configure the DDNS settings on the P-2024. Log into the WEB GUI on the P-2024 and click
Maintenance > System > Dynamic DNS to display the configuration screen as shown.

VoIP Application Notes
SIP Account Setup
P-2024 Support Notes
VoIP is the sending of voice signals over the Internet Protocol. This allows you to make phone calls and send faxes over the Internet at a fraction of the cost of using the traditional circuit-switched telephone network.
Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol that handles the setting up, altering and tearing down of voice and multimedia sessions over the Internet. SIP signaling is separate from the media for which it handles sessions. The media that is exchanged during the session can use a different path from that of the signaling. SIP handles telephone calls and can interface with traditional circuit-switched telephone networks.
The P-2024 supports up to two SIP accounts simultaneously. Follow the procedure below to configure SIP accounts on the device.
Note: You should have a voice account already set up and have VoIP information from your VoIP service provider prior to configuring a SIP account on the P-2024.

Note: Resetting the unit back to the factory defaults erases all your previous settings.
What is SUA? When should I use SUA?
SUA (Single User Account) is a unique feature supported by the P-2024 to allow more than one person to access the Internet concurrently for the cost of a single user account.
26
All contents copyright (c) 2006 ZyXEL Communications Corporation.
P-2024 Support Notes
When P-2024 acting as SUA receives a packet from a local client destined for the outside Internet, it replaces the source address in the IP packet header with its own address and the source port in the TCP or UDP header with another value chosen out of a local pool. It then recomputed the appropriate header checksums and forwards the packet to the Internet as if it originated from the P-2024 using the WAN IP address assigned by the
ISP. When reply packets from the Internet are received by the P-2024, the original IP source address and
TCP/UDP source port numbers are written back into the destination fields of the packet (since it is now moving in the opposite direction), the checksums are recomputed, and the packet is delivered to its intended destination.
This is because SUA keeps a table of the IP addresses and port numbers of the local systems currently using it.
What is the difference between NAT and SUA?
NAT is a generic name defined in RFC 1631 'The IP Network Address Translator (NAT)'. SUA (Internet
Single User Account) is ZyXEL's proprietary implementation and trade name for the PAT feature which is a specific type of NAT. SUA (or PAT for NAT) translates address into port mapping.
The primary motivation for RFC 1631 is that there is not enough IP address to go around. In addition, many corporations simply did not bother to obtain legal (globally unique) IP addresses for their networks and now finding themselves unable to connect to the Internet.
Basically, NAT is the process of translating one address to another. A NAT implementation can be as simple as substituting an IP address with another. This allows a network to solve the illegal address problem mentioned above without going through each and every host.
The goal of ZyXEL's SUA is to minimize the Internet access cost in a small office environment by using a single IP address to represent multiple hosts on the LAN. It does more than IP address translation, so that multiple hosts on the LAN can access the Internet at the same time.
How many network users does SUA/NAT support?
The P-2024 does not limit the number of the users but the number of the sessions for Internet access. The
P-2024 supports 1024 sessions. You can view the current active sessions using the 'ip nat iface enif0 disp' command in SMT menu 24.8.
What are Device and Protocol filters?
In ZyNOS, there are two filter groups: device filter and protocol filter. Generic filters belong to the device filter group while TCP/IP and IPX filters belong to the protocol filter group.

In ZyNOS, you cannot configure device filters and protocol filters in the same filter set.
Product FAQ
Will the P-2024 work with my Internet connection?
The P-2024 is designed to work with cable and ADSL modems. The P-2024 comes with an Ethernet port to connect to your computer so the P-2024 is placed between your computer and your modem. The P-2024 also supports PPPoE Internet connection type.
What do I need to use the P-2024?
Ethernet ports for LAN and WAN connection. You should connect the computer to the LAN port and the external modem to the WAN port. If the ISP uses PPPoE or Roadrunner Authentication, you need the user account to enter in the P-2024.
What is PPPoE?
PPPoE (Point-to-Point Protocol over Ethernet) is an IETF draft standard specifying how a computer interacts with a broadband modem (such as xDSL, cable, wireless, etc.) to access the high-speed data networks via a PPP dialer (such as Microsoft＇s Dial-Up Networking). PPPoE supports a broad range of applications and services including authentication, accounting, secure access and configuration management. Some ISPs still provides
PPPoE connection type today. Before configuring PPPoE in the P-2024, make sure your ISP supports PPPoE.
Does the P-2024 support PPPoE?
Yes. The P-2024 has already supported PPPoE since ZyNOS 2.50.
How do I know I am using PPPoE?
PPPoE requires a user account to log into the service provider's server. If you need to configure a user name and password on your computer to connect to the ISP, you are probably using PPPoE. If you connect to the Internet when you turn on your computer, you probably are not using PPPoE. You can also check with your ISP or the information sheet given by the ISP. Choose PPPoE as the encapsulation type in the P-2024 if the ISP uses
PPPoE.
28

Why does my provider use PPPoE?
P-2024 Support Notes
PPPoE emulates a familiar Dial-Up connection. It allows your ISP to provide services using their existing network configuration over the broadband connections. Besides, PPPoE supports a broad range of existing applications and services including authentication, accounting, secure access and configuration management.
Which Internet Applications can I use with the P-2024?
The P-2024 supports most common applications including MIRC, PPTP, ICQ, Cu-SeeMe, NetMeeting, IP/TV,
RealPlayer, VDOLive, Quake, QuakeII, QuakeIII, StarCraft, and Quick Time.
How can I configure the P-2024? a.
Telnet remote management- Menu driven user interface for easy remote management b.
Web browser- embedded web server for easy configuration
What network interface does the P-2024 support?
The P-2024 comes with a 10/100M Ethernet interface to connect to your LAN computer and the external cable/DSL modem.
What can I do with the P-2024?
You can connect to the Internet through the P-2024. This allows you to browse the web, send and receive e-mail, and download/share files. These are just a few of many benefits you get when you put the whole office on-line with the P-2024 Internet Access Sharing ATA.
Does the P-2024 support dynamic IP addressing?
Yes. You can set the P-2024 to use a static WAN IP address or set it to use a dynamic IP address from the ISP.
What is the difference between the internal IP and the real IP from my ISP?
Internal IP addresses are also referred to as virtual IP addresses. They are a group of up to 255 IP addresses that are used and recognized internally on the local area network. They are not intended to be recognized on the
Internet. The real IP address (or the public IP address) you obtain from the ISP, instead, can be recognized or pinged by other real IP addresses. The P-2024 Internet Access Sharing ATA works like an intelligent ATA that routes network traffic between the virtual IP addresses and real IP addresses.

How does e-mail work through the P-2024?
P-2024 Support Notes
It depends on what kind of IP address you have: Static or Dynamic. If your company has a domain name, it means that you have a static IP address. Suppose your company's e-mail address is [email protected]. Joe and Debbie will be able to send e-mail through the P-2024 using [email protected] and [email protected] respectively as their e-mail addresses. They will be able to retrieve their individual private and secure e-mail, if they have been assigned the proper access rights.
If your company does not have a domain name, it means that your ISP provides you with a dynamic IP address.
Suppose your company's e-mail address is [email protected]. Jane and John will be able to send e-mail through the P-2024 using "jane"<[email protected]> and "john"<[email protected]> respectively as their e-mail addresses. Again, they will be able to retrieve their individual private and secured e-mail, if they have been assigned the proper access rights.
What is the difference between the 'Standard' and 'RoadRunner' service?
The Road Runner service is commonly used in the USA and it requires the user to "log in" to the service provider network before Internet access is allowed. The most popular implementation is TAS (Toshiba
Authentication System) with a packet filtering firewall in the upstream direction. Before users are logged in, they can send ICMP packets (that is, ping) to a remote host through the Internet. However, all outgoing
(upstream) TCP and UDP packets to the Internet are blocked. Thus users can access the local local DNS/login server. Downstream packets (or packets from the Internet to the users) are not filtered or blocked.
With Standard service, no user login is required. This is commonly used with a cable modem. The P-2024 supports both Road Runner and Standard services in SMT menu 4 for connecting to the ISPs for Internet connection.
Is it possible to access a server running behind SUA from the outside Internet? If possible, how?
Yes, it is possible because P-2024 delivers the packet to the local server by looking up to a SUA server table.
Therefore, to make a local server accessible to the outside users, the port number and the inside IP address of the server must be configured in SMT Menu 15 - SUA Server Setup .
What DHCP capability does the P-2024 support?
The P-2024 supports DHCP client on the WAN por. The P-2024's DHCP client allows it to get a public WAN
IP address from the ISP automatically if your ISP uses DHCP as a method to assign IP addresses.

P-2024 Support Notes
How do I use the reset button? And which parameter will be reset by the reset button?
Use a sharp pointed object to press the reset button located near the power connector. Press and hold down the button for about five seconds to reset the device. All device settings, including the login password and IP address, will be reset to the factory defaults.
The default IP address is 192.168.5.1 and the default login password is 1234.
What network interface does the new P-2024 series support?
The new P-2024 series comes with an auto MDX/MDIX 10/100M Ethernet LAN port to connect to computer(s) or switch(es) on the LAN and one 10/100M Ethernet port to connect to the external cable/DSL modem on the
WAN.
Does the P-2024 support TFTP?
Yes. In addition to the direct console port connection, the P-2024 supports firmware upload and configuration file uploading/download using TFTP (Trivial File Transfer Protocol) over LAN.
Does the P-2024 support TFTP over WAN?
Although TFTP also works over the WAN, it is not recommended because of potential data corruption error while transferring files to the P-2024.
How can I upload data to outside Internet over the one-way cable?
Set up an alternate path for connection to the Internet (for example, a dialup connection). You can still receive downstream packets from the Internet through the P-2024.
How fast is the DSL connection?
There are a number of factors that can affect the speed of your ADSL connection. The connection speed may depend on how fast your computer handles data, how fast data can be transmitted between your computer and the modem, how well the cable modem handles traffic during network congestion, or how much bandwidth is provided by the ISP, etc.
31
All contents copyright (c) 2006 ZyXEL Communications Corporation.
P-2024 Support Notes
Depending on your computer, data process speed varies and few computers can achieve data processing rates at up to 30 Mbps.
Ethernet (10baseT) is the most popular cable modem interface standard for a computer. This automatically limits the speed of the connection to less than 10 Mbps even if the modem can receive at 30 Mbps. Most Local
Area Networks use 10baseT Ethernet, and although they are 10 Mbps networks, it takes a much longer than one second to transmit 10 megabits (or 1.25 megabytes) of data from one terminal to another.
Cable modems on the same node share the same bandwidth, which means that congestion is created when too many people try to access the Internet at the same time. In addition, when one user is downloading large graphic or video files, a significant portion of the shared bandwidth is used thus slowing down access for other users in the same neighborhood.
Most independent Internet Service Providers today connect to the Internet using a single 1.5 Mbps "T1" telephone line. All their subscribers share that 1.5 Mbps bandwidth. Cable companies connecting to the Internet backbone using a T1 limit their subscribers to an absolute maximum of 1.5 Mbps.
To create the appearance of faster network access, ISPs store or "cache" frequently requested web sites and
Usenet newsgroups on a server in the central office (CO). Storing data locally will remove some of the bottleneck at the backbone connection.
How fast can they go? Theoretically, they can receive data at speeds up to 30 Mbps. In the real world, with cost conscious cable companies running the systems, the speed will probably fall to about 1.5 Mbps.
My P-2024 cannot obtain a WAN IP address from the ISP to connect to the Internet, what should I do?
There are various ways your ISP controls user access and login. Once a user has successfully logged into, the
ISP will provide the WAN IP address to the user.
The following lists the methods ISP＇s authenticates users.
1.
Check if the modem＇s MAC address' is valid.
2.
Check if the host name is correct. The host name is usually the text after the @ sign. For example,
@home
3.
Check if the user ID is valid. This is commonly used with the RR-Toshiba Authentication and
RR-Manager Authentication services.
32
All contents copyright (c) 2006 ZyXEL Communications Corporation.
P-2024 Support Notes
If you are not able to get a WAN IP address from your ISP, check which authentication method your ISP uses and configure the settings on the P-2024. The following sections describe how you can solve this problem.
1. If your ISP checks the MAC address
Some ISPs checks the user device (usually a computer) MAC address before assigning a WAN IP address. If the MAC address matches one on the ISP＇s system, the ISP sends an IP address to the user device and allows
Internet access. However, if the user connects another computer with a different MAC address directly to the modem, the ISP discards any DHCP discovery packets from the un-authorized MAC address and no IP address is assigned.
You can set the P-2024 to copy the MAC address of the computer whose MAC address is authorized by the ISP.
The P-2024 will use the copied MAC address as its WAN MAC address.
In SMT menu 2, enter the computer MAC address. The P-2024 will use the copied MAC address as its WAN
MAC address and update SMT menu 24.1.
MAC Address:
Assigned By= IP address attached on LAN
IP Address= 192.168.5.33
Field settings: a.
Assigned By: Select IP address attached on LAN.
b.
IP Address: Enter the IP address of the computer whose MAC address is authorized by the ISP.
2. If your ISP checks the host name
Some ISPs checks the host name information contained in the DHCP request sent by the user computer. A host name is text that comes after the @ sign. For example, in [email protected], the host name is “home.com＂.
If a technician from your ISP helped you set up Internet connection, he/she set the host name as the computer name on your computer (in the Networking screen). When you connect that computer to the P-2024, you must set the same name as the P-2024＇s system name in SMT menu 1.

• System Name: Enter the same name as the computer.
3. If your ISP checks the User ID
This authentication method is used mostly by ISPs providing RoadRunner services (for example, RR-TAS
(Toshiba Authentication Service) or RR-Manager authentication). You must configure the service type, username and password exactly as provided by your ISP in SMT menu 4.

IP Address, Subnet Mask, Gateway IP Address: If you select Static in the WAN IP Address
Assignment field, enter the IP address, subnet mask and gateway device IP address provided by your ISP.
What is DDNS?
The Dynamic DNS service allows you to map a dynamic IP address to a static hostname, allowing your computer to be more easily assessable from various locations on the Internet. To use the service, you must first apply an account from one of the several free DDNS service providers such as WWW.DYNDNS.ORG
.
Without DDNS, you have to tell your users the WAN IP address of your server for them to access. It is inconvenient for the users if this IP is dynamic which changes. With DDNS supported on the P-2024, you use a
DNS name (e.g., www.zyxel.com.tw
) supplied by the DDNS service provider to your server (e.g., Web server).
Outside users can always access the web server at www.zyxel.com.tw regardless of whether the WAN IP on the
P-2024 is dynamic or static.
When the ISP assigns the P-2024 a new IP address, the P-2024 updates this IP address to the DDNS server so that the server can update its IP-to-DNS entry. Once the IP-to-DNS table in the DDNS server is updated, the
DNS name for your web server (i.e., www.zyxel.com.tw) is still easily accessible.
When do I need the DDNS service?
When you want your internal server to be accessible by using DNS name rather than using a dynamic IP address, use the DDNS service. The DDNS server maps a dynamic IP address to a static hostname. Whenever the ISP assigns you a new IP address, the P-2024 sends this IP address to the DDNS server to update its
IP-DNS table.
What DDNS servers does the P-2024 support?
Currently, the P-2024 supports WWW.DYNDNS.ORG
for DDNS service. This is the web site to which you apply the DNS and update the P-2024 WAN IP.
35
All contents copyright (c) 2006 ZyXEL Communications Corporation.
What is DDNS wildcard?
P-2024 Support Notes
Some DDNS servers support the wildcard feature which allows the *.yourhost.dyndns.org hostname to be mapped to the same IP address as yourhost.dyndns.org. This feature is useful when there are multiple internal servers and you want users to be able to use addresses such as www.yourhost.dyndns.org and still reach your server.
Does the P-2024 support DDNS wildcard?
Yes. the P-2024 supports DDNS wildcard that WWW.DynDNS.ORG
supports. To use wildcard, simply enter yourhost.dyndns.org in the Host field in SMT menu 1.1.

VoIP FAQ
What is Voice over IP?
P-2024 Support Notes
Voice over IP (VoIP) is an emerging technology based on the open IEEE standards. VoIP refers to the transmission of voice data over the Internet. Various protocols are available for voice transport. The most commonly used are SIP and H.323.
Voice over IP (VoIP) is an emerging technology based on open IEEE standards. VoIP refers to the transmission of voice data over the Internet. Various protocols are available for voice transport. The most commonly used are
SIP and H.323.
How does Voice over IP work?
In VoIP, voice data is sent digitally in discrete packets through the Internet, not through the traditional circuit switch of PSTN. To do so, an analog-to-digital converter is required at sender side to translate voice (analog signal) to digital signal before transmission. At the receiver end, an analog-to-digital converter converts the digital signal back to analog so the voice can be heard on the phone.
Why use VoIP?
Traditionally voice data is transmitted using circuit switching. Since circuit switching is designed to carry voice, it does it very well. However, as broadband networks become a mainstream for network access and technologies have evolved, we don＇t want to confine ourselves to just using text-based applications (such as e-mail, instant messaging, etc.) for communication over the Internet. Thus, the convenience of voice communication through the Internet has quickly become popular.
In addition, it would take a much longer time, more effort and money to implement new features using circuit switching. Since the IP technology is a standard and various applications are available, it is easier and more cost-effective to integrate new services and applications using IP.
What is the relationship between codec and VoIP?
In order to send voice (analog signal) over IP, it first needs to be digitized. Codec is a technique used to digitize analog signal into digital signals and vice versa. There are various speech codec available for VoIP. Each codec has its advantages and disadvantages.
37

What advantage does Voice over IP provide?
P-2024 Support Notes
VoIP provides advanced integration of text, video and voice in emails. This cannot be done using traditional circuit switching (PSTN).
What is the difference between H.323 and SIP?
H.323 and SIP are proposed by different groups. Session Initiation Protocol (SIP) is a standard introduced by the Internet Engineering Task Force in 1999 to carry voice over IP. Since it was created by the IETF, it approaches voice and multimedia from the Internet, or IP. Whereas H.323 emerged around 1996, and as an
International Telecommunication Union standard, it was designed from a telecommunications perspective. Both standards have the same objective - to enable voice and multimedia convergence with IP protocols.
Can H.323 and SIP interoperate with each other?
In interoperability between the two, the industry is making slow but sure progress. Interoperability must first happen between vendor implementations of the same protocol (SIP-to-SIP and H.323-to-H.323) and then between protocols. Currently in order for SIP client to talk to H.323 client the ITSP must have a trunking gateway act as a translator between the two protocols without the truncking gateway the two protocols are not able to communicate to one another.
What is voice quality?
Voice quality is how well a person can hear the voice on the opposite end.
How are voice quality normally rated?
Voice quality is most commonly rated through a voice quality metric called the Mean Opinion Score (MOS) which is recommendation by ITU-T. The MOS is a 5-point scale where 5 represent excellent voice quality and
1 represent bad voice quality.
What is codec?
Codec is an algorithm that converts analog signal into digital signal and vice versa. There are three codeec types: waveform, source, and hybrid codec. Each consume different amount of bandwidth and provide different voice quality.
38

What is the relationship between codec and VoIP?
P-2024 Support Notes
VoIP is the general term to refer to the sending of digitized voice information in discrete packets over public digital network (the Internet) where other data packets can be sent at the same time. A codec determines how much bandwidth voice packets will use. To save bandwidth usage, you would use as little bandwidth as possible at the cost of reduced voice quality.
What codec types does P-2024 support?
The P-2024 supports the following commonly used codecs.
• G.726
•
G.729 a/b voice codec
• G.711u-law voice codec
• G.711a-law voice codec
•
G.723.* (Option)
Which codec should I choose?
Choose a codec that is also supported on the remote VoIP host since both ends of the VoIP connection must use the same codec. In general, a codec with low bandwidth consumption and high voice quality is a good codec.
What do I need in order to use SIP?
The following lists the minimum requirement for running VoIP applications.
1. A high-speed Internet connection. You can connect to the Internet using a cable or DSL modem. Or subscribe to high-speed network services such as ISDN, DSL or T-1. The bandwidth requirement varies depending on the amount of traffic in your network.
2. A PC with VoIP software installed or an external VoIP gateway (such as an ATA or the P-2024 2602 VoIP station ATA).
3. An account from a VoIP services provider (such as an ITSP). The account can be configured to recognize your calls automatically, or you can require the users to enter their assigned unique account numbers.

I am unable to register to a SIP server
If you are unable to register to a SIP server, do the following.
P-2024 Support Notes
1. Make sure the Internet connection is up and that you are able to ping the SIP register server from the LAN behind the P-2024. If your register server uses a domain name, make sure DNS name can be resolved. If you are using a static WAN IP address, make sure the DNS server is configured correctly on your P-2024.
2. Make sure the SIP account is correct and the password is entered correctly. They may be case-sensitive.
3. Check if there is a NAT ATA install before the P-2024 which is a VoIP station gateway. It is NOT recommended that you install a NAT ATA in front of the P-2024 as this may cause unexpected problems. If you still want to install a NAT ATA, use a VoIP ATA (VoIP Analog Telephone Adapter), such as the P-2024
ATA series, instead.
I can register to the SIP server but cannot establish a call
If you are able to register to the SIP server but cannot make a call through the P-2024, it is very likely there a
NAT ATA or a firewall blocks the traffic.
It is NOT recommended that you install a NAT ATA in front of the P-2024 as this may cause unexpected problems. If you still want to install a NAT ATA, use a VoIP ATA (VoIP Analog Telephone Adapter), such as the P-2024 ATA series, instead.
I can make or receive a call but the voice traffic only goes one way, not both way
If you can register to a server and can only make an out- going call but cannot receive incoming calls or the incoming call signal establishment can be made but the voice traffic only goes one way, there is very likely a
NAT/firewall ATA installed before the P-2024. Refer to the NAT/firewall related questions for more information.
I have tried all the troubleshooting steps, but still cannot register to the SIP server. What should I do next?
In this case, contact your local service provider for support. If they cannot solve your problem, they will send your problem to the ZyXEL global technical support center. To help out the problem they will escalate your problem to ZyXEL tech center.

Trouble Shooting
Unable to Get WAN IP from ISP
My P-2024 cannot obtain an IP address from the ISP for Internet access, what should I do?
There are various ways your ISP controls user access and login. Once a user has successfully logged into, the
ISP will provide the WAN IP address to the user.
The following lists the methods ISP＇s authenticates users.
4.
Check if the modem＇s MAC address' is valid.
5.
Check if the host name is correct. The host name is usually the text after the @ sign. For example,
@home
6.
Check if the user ID is valid. This is commonly used with the RR-Toshiba Authentication and
RR-Manager Authentication services.
If you are not able to get a WAN IP address from your ISP, check which authentication method your ISP uses and configure the settings on the P-2024. The following sections describe how you can solve this problem.

P-2024 Support Notes
1. If your ISP checks the MAC address
Some ISPs checks the user device (usually a computer) MAC address before assigning a WAN IP address. If the MAC address matches one on the ISP＇s system, the ISP sends an IP address to the user device and allows
Internet access. However, if the user connects another computer with a different MAC address directly to the modem, the ISP discards any DHCP discovery packets from the un-authorized MAC address and no IP address is assigned.
You can set the P-2024 to copy the MAC address of the computer whose MAC address is authorized by the ISP.
The P-2024 will use the copied MAC address as its WAN MAC address.
In SMT menu 2, enter the computer MAC address. The P-2024 will use the copied MAC address as its
WAN MAC address and update SMT menu 24.1.
Menu 2 - WAN Setup
MAC Address:
Assigned By= IP address attached on LAN
IP Address= 192.168.5.33
Field settings:
•
•
Assigned By=, Select IP address attached on LAN .
IP Address=, Enter the IP address of the computer whose MAC address is authorized by the
ISP.
2. If your ISP checks the Host Name
Some ISPs checks the host name information contained in the DHCP request sent by the user computer. A host name is text that comes after the @ sign. For example, in [email protected], the host name is “home.com＂.
If a technician from your ISP helped you set up Internet connection, he/she set the host name as the computer

• System Name: Enter the same name as the compute name on the computer.
3. If your ISP checks the User ID
This authentication method is used mostly by ISPs providing RoadRunner services (for example, RR-TAS
(Toshiba Authentication Service) or RR-Manager authentication). You must configure the service type, username and password exactly as provided by your ISP in SMT menu 4.

Using Embedded Packet Trace
Embedded Packet Trace
P-2024 Support Notes
The P-2024 packet trace feature records and analyzes packets running on the LAN and WAN interfaces. It is designed for technical users who are interested in the details of the packet flow on the P-2024＇s LAN or WAN interface. It is also a diagnostic tool if you have compatibility problems with your ISP or if you want to know the details of a packet for configuring a filter rule.
The format of the packet trace result display is as follows:
Packet:
0 11880.160 ENET0-R[0062] TCP 192.168.1.2:1108->192.31.7.130:80
[index] [timer/second][channel-receive/transmit][length] [protocol] [sourceIP/port] [destIP/port]
There are two ways to view the trace result:
1.
Online Trace--display the trace real time on screen
2.
Offline Trace--capture the trace first and display later
The following details the trace commands in SMT menu 24.8.
Online Trace
1. Trace LAN packet
2. Trace WAN packet
1. Trace LAN packet
1.1 Disable WAN packet trace: sys trcp channel enet1 none
1.2 Enable LAN packet trace: sys trcp channel enet0 bothway
1.3 Enable trace logging: sys trcp sw on & sys trcl sw on

LAN/WAN Packet Trace
62
All contents copyright (c) 2006 ZyXEL Communications Corporation.
P-2024 Support Notes
You can use the packet trace feature on the P-2024 to record and analyze packets transmitting through the LAN and WAN interfaces. It is designed for technical users who are interested in the details of the packet flow on the
P-2024＇s LAN or WAN interface. It is also a very helpful diagnostic tool to solve Internet connection problems or if you want to know the details of a packet for configuring a filter rule.
The format of the result is displayed as follows:
Packet:
0 11880.160 ENET0-R[0062] TCP 192.168.1.2:1108->192.31.7.130:80
[index] [timer/second][channel-receive/transmit][length] [protocol] [sourceIP/port] [destIP/port]
There are two ways to display the trace results:
1.
Online Trace--display real-time trace results on the screen
2.
Offline Trace-- save the trace results first and display them later
The following shows you how to obtain and display the packet trace results in SMT menu 24.8 are as follows.
Online Trace
1. Trace LAN packet
2. Trace WAN packet
1. Trace LAN packet
1.1 Disable capture the WAN packet trace: sys trcp channel mpoa00 none
1.2 Enable capture the LAN packet trace: sys trcp channel enet0 bothway
1.3 Enable trace logging: sys trcp sw on & sys trcl sw on
1.4 Display brief online trace results: sys trcd brief or
1.5 Display detailed online trace results: sys trcd parse
Example: ras> sys trcp channel mpoa00 none
