Hello everyone,

Since a few days I have a problem, opnsense blocks all LAN traffic to the outside.
Any ideas.

Yes, well that does not tell me much as all the WAN stuff is redacted. ???


Whatever. it appears there are no strange blocks that I can see, but there are few things to look at.


Let's start with some diagnostics... try this, do you get a response?

I assume what I see there is the port forward rule...


What about the associated rule in the firewall WAN rule settings?

Yep.. I cannot see anything wrong there. Try deleting the 8080 rule and creating it as a floating rule, see if that works.

I have all tried, there is not only problem. Also when i connect in ssh on a remote server it blocks me....


example : I allowed all outgoing LAN traffic, but it blocks as even the outgoing traffic (it's variant)

SSH is not open by default on the WAN interface, and I don't advise you do so. If you want to connect remotely to the firewall the secure method is to use VPN and then use a SSH.

If you like, you can pm me your rules.debug file, I'll see if there is something there I may be missing when looking at your rules.
