I am using “yast firewall” at the command line on a server I have set up for VOIP. I have set the interface to external zone as it is directly connected to the internet and has public IP assigned. In “Allowed Services” I have deleted HTTP Server and HTTPS Server and restarted firewall. Why can I still access webpages on my server?
Just found the answer. Port 80 was specified in TCP Ports in Advanced under Allowed Services.
