I’m trying to connect a device to our network that I’m having problems with. The vendor sent back:
“It looks like your firewall needs to allow Trigger Ports 8000-20000 open. Those are the data ports that allow the actual audio data through, different from Port Forwarding.”
I have done some searches on Port Triggering and haven’t had a lot of luck.. Can anyone point me in the right direct?
Thanks,
Mike
Maybe you should explain everything. Exactly what you are trying to do.
Because as is you should have no issue.
The default Mikrotik firewall rules allow triggering.
0 ;;; default configuration
chain=input action=accept protocol=icmp
1 ;;; default configuration
chain=input action=accept connection-state=established
2 ;;; default configuration
chain=input action=accept connection-state=related
3 ;;; default configuration
chain=input action=drop in-interface=Ether1
Notice rule 1 and 2. They both allow any incoming connection though that is part of an established or related connection.
Example I connect to Teamspeak udp 9987 the router establishes that connection. I can receive incoming on that port as long as the connection (Application) is open. This is triggering as I triggered the port by connecting to the Teamspeak server.
