Tested SUA/NAT Applications (e.g., Cu-SeeMe, ICQ, NetMeeting)

- Introduction

Generally, SUA makes your LAN appear as a single machine to the outside world. LAN users are invisible to outside users. However, some applications such as Cu-SeeMe, and ICQ will need to connect to the local user behind the Prestige. In such case, a SUA server must be entered in menu 15 to forward the incoming packets to the true destination behind SUA. Generally, we do not need extra settings of menu 15 for an outgoing connection. But for some applications we need to configure the menu 15 to make the outgoing connection work. After the required menu 15 settings are completed the internal server or client applications can be accessed by using the Prestige's WAN IP address.

- SUA Supporting Table

The following are the required menu 15 settings for the various applications running SUA mode.

1 Since SUA enables your LAN to appear as a single computer to the Internet, it is not possible to configure similar servers on the same LAN behind SUA. For example, you can have two WEB servers using TCP:80 in the same LAN. They must have different port numbers.

2 Because White Pine Cu-SeeMe uses dedicate ports (port 7648 & port 24032) to transmit and receive data, therefore only one local Cu-SeeMe is allowed within the same LAN.

3 In SUA mode, the remote NetMeeting user is allowed to connect only one local user, it is because the outsiders can not distinguish between local users using the same internet IP. However, the local user can connect to multiple remote users.

4 Certain Quake servers do not allow multiple users to login using the same unique IP, so only one Quake user will be allowed in this case. Moreover, when a Quake server is configured behind SUA, Prestige will not be able to provide information of that server on the internet.

5 Quake II has the same limitations as that of Quake I.

6 Prestige series support MSN Messenger 4.6/ 4.7/ 5.0 video/ voice pass-through NAT. In addition, for the Windows OS supported UPnP (Universal Plug and Play), such as Windows XP and Windows ME, UPnP supported in Prestige is an alternative solution to pass through MSN Messenger video/ voice traffic. The following model and firmware support UPnP function. For mote detail, please refer to UPnP application note.

7 Prestige series support Microsoft Xbox Live since V3.52 firmware version. If your firmware is too old to support such function, you may have a work-around solution, please refer to ZyXEL website -> Support -> Xbox Live service http://www.zyxel.com/support/xbox.htm

- Notes

1. In 1.5x and 2.2x versions, if a SMTP (port 25) server is configured in menu 15 the POP3 ( port 110) packets will also be forwarded to the same SMTP server by the Prestige automatically. There is no need to configure additional POP3 server in menu 15, unlike 2.2x and 1.5x versions, SMTP & POP3 servers are handled by the Prestige separately in V2.3 and above versions. So, two ports (25 & 110) must be configured in menu 15 to support both SMTP and POP3 services.
2. NetMeeting, RealPlayer, IP/TV and Quick Time are supported in V2.3 and above versions.

- Configurations

For example, if the workstation operating Cu-SeeMe has an IP of 192.168.1.34, then the default SUA server must be set to 192.168.1.34. The peer Cu-SeeMe user can reach this workstation by using Prestige's WAN IP address which can be obtained from menu 24.1.

`Menu 15 - SUA Server Setup` `Port # IP Address` `------ ---------------` `1.Default 192.168.1.34` `2. 0 0.0.0.0` `3. 0 0.0.0.0` `4. 0 0.0.0.0` `5. 0 0.0.0.0` `6. 0 0.0.0.0` `7. 0 0.0.0.0` `8. 0 0.0.0.0` ``
