Configure Port Triggering
Port triggering allows some applications running on a LAN network to be available to external
applications that would otherwise be partially blocked by the firewall. Using the port-triggering
feature requires that you know the port numbers used by the application.
Once configured, port triggering operates as follows:
1.
A PC makes an outgoing connection using a port number that is defined in the Port
Triggering Rules table.
2.
The UTM records this connection, opens the additional incoming port or ports that are
associated with the rule in the port triggering table, and associates them with the PC.
3.
The remote system receives the PC's request and responds using the incoming port or ports
that are associated with the rule in the port triggering table on the UTM.
4.
The UTM matches the response to the previous request and forwards the response to the
PC.
Without port triggering, the response from the external application would be treated as a new
connection request rather than a response to a request from the LAN network. As such, it
would be handled in accordance with the inbound port-forwarding rules, and most likely
would be blocked.
