We've a small network with one server, three clients, Internet router (separate), no domain, no DNS. All devices are connected by a bridge on the firewall. As soon as the IP firewall (set use-ip-firewall=yes) for the bridge is enabled, it's no longer possible to ping the hosts by name. It doesn't matter which rules on the firewall are set, I've tried with allow all, without rules, without drops, the result is still the same, ping by hostname doesn't work if IP firewall is enabled.
One of the clients responds with IPv6 packets, that works, no matter which rules are enabled, also for IPv6, it works.
I'm trying since many hours, but I can't find a solution. Actually I use the local hosts file, but it should work without.
Does anybody know how to configure the firewall to allow the Windows short name resolution?
