Some applications require multiple connections, such as Internet gaming, video conferencing,
Internet telephony and others. These applications cannot work when Network Address Transla-
tion (NAT) is enabled. If you need to run applications that require multiple connections, specify
the port normally associated with an application in the "Trigger Port" field, select the protocol
type as TCP or UDP, then enter the public ports associated with the trigger port to open them
for inbound traffic.
For example:
ID Trigger Port
Trigger
Type
Public Port Public Type Comment
1 28800 UDP 2300-2400, 47624 UDP MSN Game Zone
2 28800 UDP 2300-2400, 47624 TCP MSN Game Zone
3 6112 UDP 6112 UDP Battle.net
4.5.2 Virtual Server
If you configure the Router as a virtual server, remote users accessing services such as Web
or FTP at your local site via public IP addresses can be automatically redirected to local serv-
ers configured with private IP address. In other words, depending on the requested service
(port number), the Router redirects the external service request to the appropriate server.
For example:
ID Mapping Ports Server IP Enabled
1 200 192.168.2.20
2 333 192.168.2.12
3 455 192.168.2.28
