Very strange NAT problem

[tverweij]

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?

I found a solution - or better: work around.

After the restart of the firewall, wait one or two minutes and then login, go to the Dashboard and restart the Packet Filter and the System Routing.
And then everything works again.
