Situation is, installed nethserver 6.8 on a vps with only green nic.
I also installed icewarp mail server (comes with custom apache for mail-client) and disabled postfix.
Now when I have ssl access to this mail client, I wanted to disable port 80 via firewall.
In firewall objects, services port 80.
In firewall rules, reject from any to any, service http.
Unfortunately, I still have access via http://
At the moment, it seems, port 80 ist closed to outside, and not to inside.
Maybe someone can describe me, how to handle firewall with only green interface?
“Trusted network” of course is also my green interface into wan.
Update: when rule is source:red and dest:green, service http, internet is reachable from inside.
