Example: Special Applications

If you need to run applications that require multiple connections, then specify the port (outbound) normally associated with

that application in the "Trigger Port" field. Then select the protocol type (TCP or UDP) and enter the public ports associated

with the trigger port to open them up for inbound traffic.

Example:

ID

Trigger Port

Trigger Type

Public Port

Public Type

Comment

1

28800

UDP

2300-2400, 47624

TCP

MSN Game Zone

2

6112

UDP

6112

Battle.net

In the example above, when a user trigger’s port 28800 (outbound) for MSN Game Zone then the router will allow incoming

packets for ports 2300-2400 and 47624 to be directed to that user.
