your network. Prestige's design helps users to save expenses, minimize maintenance, and simultaneously provide a high quality networking environment.

The P320W is a robust solution complete with everything needed for providing Internet access to multiple workstations through your cable or ADSL modem. The router equipped with 1 10/100Mbps Ethernet

WAN port and 4 10/100Mbps Ethernet LAN port.

Virtually all-popular applications over Internet, such as Web, E-Mail, FTP, Telnet, Gopher, are supported.

Will the P320W work with my Internet connection?

The P320W is designed to be compatible with cable and ADSL modems. Most external Cable and ADSL modems use an Ethernet port to connect to your computer so the Prestige is placed in the line between the computer and the External modem. As long as your Internet Access device has an Ethernet port, you can use the Prestige. Besides, if your ISP supports PPPoE you can also use the Prestige, because PPPoE had been supported in the Prestige.

What do I need to use the Prestige?

You need an ADSL modem or cable modem with an Ethernet port to use the Prestige. The Prestige has two Ethernet ports: LAN port and WAN port. You should connect the computer to the LAN port and connect the external modem to the WAN port.

What is PPPoE?

PPPoE stands for Point-to-Point Protocol Over Ethernet that is an IETF draft standard specifying how a computer interacts with a broadband modem (i.e. xDSL, cable, wireless, etc.) to achieve access to the high-speed data networks via a familiar PPP dialer such as 'Dial-Up Networking' user interface. PPPoE supports a broad range of existing applications and service including authentication, accounting, secure access and configuration management. There are some service providers running of PPPoE today. Before configuring PPPoE in the Prestige, please make sure your ISP supports PPPoE.

Does the Prestige support PPPoE?

Yes. The Prestige supports PPPoE.

How do I know I am using PPPoE?

P320W Support Notes

PPPoE requires a user account to login to the 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 are simply connected to the Internet when you turn on your computer, you probably are not. You can also check your

ISP or the information sheet given by the ISP. Please choose PPPoE as the encapsulation type in the

Prestige if the ISP uses PPPoE.

Why does my provider use PPPoE?

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 service including authentication, accounting, secure access and configuration management.

Which Internet Applications can I use with the Prestige?

Most common applications include MIRC, PPTP, ICQ, Cu- SeeMe, NetMeeting, IP/TV, RealPlayer,

VDOLive, Quake, Quake11, Quake111, StarCraft, & Quick Time.

How can I configure the Prestige?

Web browser- web server embedded for easy configurations

What network interface does the Prestige support?

The Prestige supports 4*10/100M Ethernet to connect to the computer and 10M Ethernet to connect to the external cable or ADSL modem..

What can we do with Prestige?

Browse the World Wide Web (WWW), send and receive individual e-mail, and download software.

These are just a few of many benefits you can enjoy when you put the whole office on-line with the

Prestige Internet Security Gateway.

Does Prestige support dynamic IP addressing?

The Prestige supports either a static or dynamic IP address from ISP.

What is the difference between the internal IP and the real IP from my ISP?

Internal IPs are sometimes referred to as virtual IPs. They are a group of up to 255 IPs that are used and recognized internally on the local area network. They are not intended to be recognized on the Internet.

The real IP from ISP, instead, can be recognized or pinged by another real IP. The Prestige Internet

Access Sharing Router works like an intelligent router that route between the virtual IP and the real IP.

How does e-mail work through the Prestige?

It depends on what kind of IP 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 Prestige Internet Access Sharing Router 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 right.

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 Prestige Internet Access Sharing Router 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 right.

What is the main difference between WinGate and the Prestige?

1. WinGate is a software only solution that needs to be installed in a dedicated Windows 95 PC based server. The total cost and complexity are many times over ATI’s product. The Prestige

Internet Access Sharing Router is a plug-n-play internet appliance.

2. WinGate requires all TCP/IP applications such as Netscape Navigator to be reconfigured to have the dedicated server as a proxy. The Prestige Internet Access Sharing Router does not require users to reconfigure any software at all.

3. The Prestige Internet Access Sharing Router uses Network Address Translation (NAT) scheme, which supports all TCP/UDP ports. WinGate only supports limited number of ports, such as http(80), ftp(21), telnet(23), and pop3(110).

4. WinGate works as a proxy, while the Prestige Internet Access Sharing Router works as a gateway.

The gateway approach is more efficient than the proxy during the processing of TCP/IP commands. As a result, the Prestige Internet Access Sharing Router achieves 10% to 20% higher performance than that of software solutions such as WinGate.

5. The Prestige Internet Access Sharing Router uses Solid State Disk technology. There are no moving parts in the product. It is much more reliable than any hard disk based system, such as the one for WinGate.

Is it possible to access a server running behind SUA from the outside Internet? If possible, how?

Yes, it is possible because Prestige 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 Network>NAT>Port Forwarding

What DHCP capability does the Prestige support?

The Prestige supports DHCP client on the WAN port and DHCP server on the LAN port. The Prestige's

DHCP client allows it to get the Internet IP address from ISP automatically. The Prestige's DHCP server allows it to automatically assign IP and DNS addresses to the clients on the local LAN.

What network interface does the new Prestige series support?

The Prestige series support 4*10/100M Ethernet LAN port to connect to the computer on LAN and

1*10/100M Ethernet to connect to the external cable or ADSL modem on WAN.

How can I upload data to outside Internet over the one-way cable?

A workaround is to use an alternate path for your upstream path, such as a dialup connection to an

Internet service provider. So, if you can find another way to get your upstream packets to the Internet you will still be able to receive downstream packets via Prestige.

How fast can the data go?

The speed of the cable modem is only one part of the equation. There are a combination of factors starting with how fast your PC can handle IP traffic, then how fast your PC to cable modem interface is, then how fast the cable modem system runs and how much congestion there is on the cable network, then how big a pipe there is at the head end to the rest of the Internet.

Different models of PCs and Macs are able to handle IP traffic at varying speeds. Very few can handle it at 30 Mbps.

P320W Support Notes

Ethernet (10baseT) is the most popular cable modem interface standard for the PC. This automatically limits the speed of the connection to under 10 Mbps even if the cable modem can receive at 30 Mbps.

Most Local Area Networks use 10baseT Ethernet, and although they are 10 Mbps networks, it takes a

LOT 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 bandwidth, which means that congestion is created when too many people are on simultaneously. One user downloading large graphic or video files can use a significant portion of shared bandwidth, 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 of their subscribers share that 1.5 Mbps pipeline. Cable head-ends 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, service companies plan to store or "cache" frequently requested web sites and Usenet newsgroups on a server at their head-end. Storing data locally will remove some of the bottleneck at the backbone connection.

How fast can they go? In a perfect world (or lab) 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 Prestige can not get an IP address from the ISP to connect to the Internet, what can I do?

Currently, there are various ways that ISPs control their users. That is, the WAN IP is provided only when the user is checked as an authorized user. The ISPs currently use two ways:

1. Check if the 'MAC address' is valid

2. Check if the 'Host Name' is valid, e.g., @home

If you are not able to get the Internet IP from the ISP, check which authentication method your ISP uses and troubleshoot the problem as described below.

1. Your ISP checks the 'MAC address'

Some ISPs only provide an IP address to the user with an authorized MAC address. This authorized MAC can be the PC's MAC which is used by the ISP for the authentication. So, if a new network card is used or

P320W Support Notes

the Prestige is attached to the cable modem directly, the ISP will reject the DHCP discovery from this

MAC, thus no IP is assigned by the ISP.

The Prestige supports to clone the MAC from the first PC the ISP installed to be its WAN MAC. To clone the MAC from the PC you need to enter that PC's IP in Network > WAN > Internet Connection. Once the

MAC is received by the Prestige, the WAN MAC will be updated and used for the ISP's authentication.

2. Your ISP checks the 'Host Name'

Some ISPs take advantage of the 'host name' message in a DHCP packet such as @home to do the authentication. When first installing, the ISP's tech people configure the host name as the 'Computer

Name' of the PC in the 'Networking' settings. When the Prestige is attached to the cable modem to connect to the ISP, we should configure this host name in the Prestige's system.

What is BOOTP/DHCP

BOOTP stands for Bootstrap Protocol. DHCP stands for Dynamic Host Configuration Protocol. Both are mechanisms to dynamically assign an IP address for a TCP/IP client by the server. In this case, the

Prestige Internet Access Sharing Router is a BOOTP/DHCP server. Win95 and WinNT clients use DHCP to request an internal IP address, while WFW and WinSock clients use BOOTP. TCP/IP clients may specify their own IP or utilize BOOTP/DHCP to request an IP address.

What is DDNS

The Dynamic DNS service allows you to alias a dynamic IP address to a static hostname, allowing your computer to be more easily accessed from various locations on the Internet. To use the service, you must first apply an account from several free Web servers such as WWW.DYNDNS.ORG

.

Without DDNS, we always tell the users to use the WAN IP of the Prestige to reach our internal server. It is inconvenient for the users if this IP is dynamic. With DDNS supported by the Prestige, you apply a

DNS name (e.g., www.zyxel.com.tw) for your server (e.g., Web server) from a DDNS server. The outside users can always access the web server using the www.zyxel.com.tw regardless of the WAN IP of the

Prestige.

57

P320W Support Notes

When the ISP assigns the Prestige a new IP, the Prestige updates this IP to 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 usable.

When do I need DDNS service?

When you want your internal server to be accessed by using DNS name rather than using the dynamic IP address we can use the DDNS service. The DDNS server allows to alias a dynamic IP address to a static hostname. Whenever the ISP assigns you a new IP, the Prestige sends this IP to the DDNS server for its updates.

What DDNS servers does the Prestige support?

The DDNS servers the Prestige supports currently is WWW.DYNDNS.ORG

where you apply the DNS from and update the WAN IP to.

What is DDNS wildcard?

Some DDNS servers support the wildcard feature which allows the hostname, *.yourhost.dyndns.org, to be aliased to the same IP address as yourhost.dyndns.org. This feature is useful when there are multiple servers inside and you want users to be able to use things such as www.yourhost.dyndns.org and still reach your hostname.

Does the Prestige support DDNS wildcard?

Yes, the Prestige supports DDNS wildcard that WWW.DynDNS.ORG

supports. When using wildcard, you simply enter yourhost.dyndns.org in the Host field in Dynamic DNS page.

Why can't I use video conferencing with MSN 4.6?

This is because MSN 4.6 requires support of UPnP (Universal plug n’ play). To be able to use MSN through Prestige, you have to enable the UPnP feature under Management-> UPNP and Check the enable

UPnP check box and press "Apply button" to make it active.

Should I create any firewall rule by myself to allow incoming traffic when NAT is used?

Built-in firewall function is supported in P320W. When a session is initiated from a user located in

P320W's LAN network, incoming traffic will be allowed by Stateful Inspection mechanism. However, if the session is initiated from WAN side and there is no related access rule for the incoming traffic, the
