Lost Communication Randomly with 21.7.7

[filmar]

Hi,

My config has 3 ports :

WAN
LAN
DMZ

The LAN is configured to use IPv4 and this port is connected to Asus RT-AC68U. The Asus is also configured to use IPv4, not v6.

Since I updated to 21.7.7, I don't understand why because I have no log about that, my LAN stop communicates. But the system still responding from outside. I have a website on DMZ and it is responding. So it is just my LAN port that randomly stop communicates.

If I physically disconnect and reconnect the cable behind Asus, the communication start working again until next down. This morning I must did that 3 times.

Tonight I got another down, I try another test. I went to the OpnSense directly and by the menu I restart all services and the communication start working again.

I conclude that it is not a physical problem because before 21.7.7, I don't have this problem, and by restarting all services it is working again.

May be I missing something about a configuration that I have to make with 21.7.7 ?

Thank you for your help !

Ok, today the problem occurs not on LAN, but on DMZ.

Just unplug and reconnect solved the problem...

To help those that may be encountered some behavior like mine, finally, my problem was the PCI x1 with 4 ports. I have bought this card

After one year of service, it was starting to get instability.

So I replace it by two cards :

Now all is stable.
