Server not visible on the server browser for others or me

Nor accessible through manually typing the address. But the weird thing is that I can access the server. Is it due to me specifying an internal address in server.cfg?

1. If server is at home, set up port forwarding on your router. The port is 26000 UDP & TCP and it needs to point to your server IP.
2. Configure firewall on your server or disable it all together (iptables -I INPUT -j ACCEPT && echo 0 > /selinux/enforce)
3. Put the following into your server.cfg: sv_public 1
