Pakets from the same source will be blocked some times some times not

[wgloes]

Hi,

I've a very strange behavior. HTTPS packets are going through the FW and some seconds later are going to be blocked (see screenshot). It looks like this is affecting only some kinds of packets. The mentioned HTTPS packets are affected, SSH packets too (SSH connections are disconnected every some seconds). In summary we are speaking from TCP connections I think. ICMP packets to the same destination are going through without interruption.
Any ideas?

Best regards.

OK, I found out that the solution is https://pfsense-docs.readthedocs.io/en/latest/firewall/troubleshooting-blocked-log-entries-due-to-asymmetric-routing.html.

Very strange because no one of the described scenario is matching with my environment  . I've only one configured gateway for the WAN interface, I've some static routes because of another router behind the firewall, but all of them behind the WAN interface.

I've configured now the rules from internal LAN to the management network according the mentioned URL.
Is anybody there to help me to find out the reason because of that?
