Hi guys, I know its an old topic but I have exactly the same issue in 7.1.3 with IPv6 Gateway for br0 is always fd00::1. In Unraid itself the router IP is set as gateway and in the Docker settings the router IP is also shown as gateway, but br0 always gets fd00::1 as gateway. Tried macvlan and ipvlan and deleted br0 and let Unraid create it new.
