How to Configure and Use APF Firewall
What is APF?
Advanced Policy Firewall, or APF, is a firewall sometimes seen on Liquid Web’s servers. It is basically an interface to iptables, which is the standard interface to managing network ports on Linux machines. Interacting with iptables can be complex and error-prone, and APF greatly simplifies working with it. However, APF is still only accessible by ssh. There is no way to make changes in APF through WHM or cPanel.
