NAT Applications Compatibility

Introduction

NAT (also known as Single User Account or SUA) makes your local network appear as a single machine to the outside world. LAN users are invisible to outside users. However, some applications such as CuSeeMe and ICQ will need to connect to a local user behind the router. In such cases, an SUA server must be declared in the router's internal Manager Menu 15 to allow forwarding of incoming packets to the true destination behind the router. After the required Menu 15 settings are completed the internal server or client applications can be accessed by using the router's WAN IP address.

NAT Support Table

There are required Menu 15 settings for the following applications running NAT (SUA) mode.

Traffic Type	Application Version	Required Settings in Menu 15 Port/IP
Traffic Type	Application Version	Outgoing Connection	Incoming Connection
HTTP	Netscape, IE	None	80/client IP
FTP	Windows FTP, Cuteftp	None	21/client IP
TELNET	Windows Telnet, Neterm	None	23/client IP (and remove Telnet filter in WAN port)
POP3	Eudora	None	110/clinet IP
SMTP	Eudora	None	25/client IP
mIRC	mIRC	None	.
PPTP	Windows PPTP	None	1723/client IP
ICQ	ICQ 99a	None for Chat. For file transfer, we must enable: ICQ -> preference -> connections -> firewall and set the firewall time out to 80 seconds in firewall setting.	Default/client IP
Cu-SeeMe^²	Cornell 1.1	None	7648/client IP
.	White Pine 3.1.2	7648/client IP & 24032/client IP	Default/client IP
.	White Pine 4.0 (CuSeeMe Pro )	7648/client IP & 24032/client IP	Default/client IP
NetMeeting^³	Microsoft NetMeeting 2.1 & 2.11	None	1720/client IP 1503/client IP
IP/TV	Cisco IP/TV 2.0.0	None	.
RealPlayer	RealPlayer G2	None	.
VDOLive	.	None	.
Quake I^⁴	Quake1.06	None	Default/client IP
QuakeII^⁵	QuakeII2.30	None	Default/client IP
QuakeIII	QuakeIII1.05 beta	None	.
StartCraft	.	6112/client IP	.
Quick Time	Quick Time 4.0	None	.

^¹ Since SUA enables your LAN appear to be a single computer to the Internet, it is not possible to configure similar servers on the same LAN behind SUA.

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

^³ With NAT enabled, NetMeeting users within the same LAN will not be able to connect to the same remote NetMeeting user. As the remote user is not able to distinguish between local users with the same internet IP. But NAT 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. In addition, when a Quake server is configured behind NAT, the router 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.

Configurations

For example, if the workstation operating CuSeeMe has an IP of 192.168.0.3, then the default SUA server must be set to 192.168.0.3. The peer CuSeeMe user can reach this workstation by using the router's WAN IP address which can be obtained from Menu 24.1.
