Try again on release. If you can still reproduce it there, provide more information about the configuration for whichever interface igb3 is on that firewall.

I will try it tomorrow.
I was moving the modem to another location, so I had to connect a longer cable.
I connected and disconnected wan port several times and at one point connected the wrong cable too (IPMI cable).
So, it might have been one of those rare bugs that are hard to reproduce.
igb3 is my wan port.
