Ubuntu Iptables


Recommended Posts

Is someone willing to share how they configured their iptables? I'm trying to set 'em up on Ubuntu Server 12.04 LTS; for the first time on a linux distro. Particularly, do I need any other rules in addition to:


sudo iptables -A INPUT -p tcp --dport [port] -j ACCEPT


for ports 80, 443, 5060, 5061, 123, 389; and


sudo iptables -A INPUT -p udp --dport [port] -j ACCEPT


for ports 5060, 16384:16484
