Title: Very strange NAT problem
Post by: tverweij on October 20, 2025, 04:42:34 PM
It started around februari 2025, suddenly, after a reboot of the firewall the NAT rules did not work anymore.
All rules have the logging on, but when I check in the live log, I don't even see any incoming connection, not accepted and not denied.
Other connections work as they should, only NAT doesn't work.

I checked, checked and checked again, removed contraints, recreated the rules, no avail.

But then: after about 4 hours (after the reboot) everything suddenly starts to work again.
Without me doing anything ....

And this is at EVERY reboot of the opnsense firewall.

Somebody? Any suggestions?
