Sorry for the late reply. I fixed it by switching my docker network from IPVLAN to MACVLAN and adding DHCP reservations for each container MAC in the router DHCP table.

25.7, 25.10 Series / [SOLVED] After upgrade, cannot ping docker container static IPs
October 03, 2025, 12:26:40 PM
My firewall was offline for about 4 months due to shipping, I believe the old version was probably 25.1.6 or close to it, and I just upgraded it to current [25.7.4]. Before I upgrade, all my docker containers that have static IPs could access the internet. After the upgrade, they can't. So something changed but I don't know what it is. The docker network uses ipvlan which doesn't allow setting MAC addresses for the static IPs so pulling an IP from DHCP is not an option.
I tried changing to macvlan on the docker host but that had it's own issues which are separate from this problem.
If I change the network setting on the docker containers to use the docker host IP, then the router can ping them and vice versa.
Does anyone know what setting in the firewall would cause this behavior. Of note, I have two other docker hosts running exactly the same way but using pfsense router, and this behavior does not occur.
Thanks!
