MBR W40 – Admin’s Manual
61
The firewall blocks inbound traffic by default.
The server replies to W40 IP, and the connection is not sent back to your host, since it is not part of a session.
In order to solve this you need to define a Port Triggering entry, which allows inbound traffic on UDP port 3333 only
after a LAN host generated traffic to UDP port 2222. This will result in accepting the inbound traffic from the gaming
server and sending it back to the LAN Host which originated the outgoing traffic to UDP port 2222. Select the 'Port
Triggering tab in the Security management screen. The Port Triggering screen will appear (see Figure 70). This screen
will list all of the port triggering entries.

 To add an entry for the gaming example above:
1. Select the User Defined option in the Protocol column to add an entry. The Edit Port Triggering Rule screen
will appear (see Figure 71).

2. Enter a name for the service (e.g. "game_server")
3. Click the New Trigger Ports link. The Edit Service Server Ports screen will appear (see Figure 70).
