I am migrating from opensuse to nethserver. Actual I am working on migrating my firewall settings.
I have seen that you can do some settings at the network services tab. But there you can only allow or deny dovecot with all ports(110,143,4190,993,995). Same thing with HTTP. I want to allow only secure ports.
I tested with creating a firewall rule with deny on port 110, but that didn’t work. I think because the network settings override my own firewall rule.
Is there any way to implement this?
By the way if you create a zone with the same subnet as your eth0 or eth1 the nethserver isn’t reachable anymore until you stop the shorewall service. Perhaps you can check this and give out a error message if somebody would like to do that.
Hope you can help me.
