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 ZyAIR. 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 ZyAIR's WAN IP address.

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.

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 With SUA enabled, NetMeeting users within the same LAN will not be able to connect to the remote NetMeeting user, and as remote users are not able to distinguish between local users with the same internet IP and SUA allows one local NetMeeting user to connect to multiple Internet users at the same time.

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, ZyAIR 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 The voice service of MSN Messenger 4.6 require UPnP (Universal Plug and Play) feature to dynamically allocate TCP/ UDP port. The configuration is shown as below.

- 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 ZyAIR 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 ZyAIR 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/ NAT server must be set to 192.168.1.34. The peer Cu-SeeMe user can reach this workstation by using ZyAIR's WAN IP address which can be obtained from menu 24.1.

`` `Menu 15.2 - NAT Server Setup Rule Start Port No. End Port No. IP Address --------------------------------------------------- 1.
