Port Forwarding with OPNSense

[miguelr]

Almost the same issue, except I only have a modem directly to the firewall

Basically, I try to do port forwarding, and no matter what I do(and it applies the right rules in the WAN tab of the firewall), it does not work.

Do you need me to provide anything?
