I'm on OPNsense 18.7.8, and I have a port forward rule that doesn't seem to work, and I'm not sure why.
WAN TCP/UDP * * WAN address 2400 192.168.1.200 2400 <--Works fine
WAN TCP * * WAN address 2222 192.168.1.100 2222 <--Connection timeout
The service on 192.168.1.100:2222 responds fine if I'm on the LAN. And it is definitely TCP-only, as it is an SSH-based service. But I have tried changing it to TCP/UDP, but it made no difference.
The port forward that works fine is used for an automated system with a remote client, so I have no way to manually confirm that it is working, I just have to take the reports' word for it. Which is "Yes, the service is accessible."
I don't know exactly what to look for in the logs. If someone could give me a clue on that one, I can go poke around in there and see if maybe the firewall is acting like this rule doesn't exist or something.
Any suggestions?
Thanks!
do you have also a rule on the lan interface for port 2222/tcp?
