There are tons of example iptables examples out there though I always recommend people to review and tailor the ruleset for their own needs. One such non-AMPR example is the IP Masquerade HOWTO example: http://www.tldp.org/HOWTO/IP-Masquerade-HOWTO/stronger-firewall-examples.ht… The above example is distribution agnostic so it should work on your preferred flavor but there can be benefits of adapting it to either your distribution's native firewall syntax or to some higher level tool that incorporates features like QoS, etc (shorewall, etc). I'm willing to take a stab at putting a baseline config into the Wiki but give me a bit to troll through the archives, review various people's submitted configs, etc. and hopefully come up a config that will work for most base deployments. --David KI6ZHD
