So I have a server running Docker. I have the server's IP address in as a gateway with a route to one of hte docker subnets. This works great except since 22.7 the server can no longer get DNS from the router.
The router replies back with 0.0.0.0.53 as the source when I'm checking my packet captures. If I change the IP address of the server but leave the gateway the same it's fine. Then I can change the gateway to the new server IP, but after the next reboot the issue starts again.
Interface Capture output

10.0.1.5 is my internal Gateway that I have a single route to.
I notice in the state table all these states show "NO_Traffic:Single". The firewall rule I found for the 0.0.0.0.53 > 10.0.1.5 states all used the "let anything out from firewall" rule.
