I prefer to utilize Advanced Policy Firewall (http://www.rfxn.com/projects/advanced-policy-firewall) on my server, which works with iptables just like native Linux Firewall provided by Virtualmin by default (Webmin -> Networking -> Linux Firewall) does. I wonder do they conflict with each other? Is it better and safer to turn Linux Firewall if I prefer to use APF?
Thanks!
