Simple IPTABLES firewall 0.6

Simple IPTABLES firewall is a very simple firewall constructed with basic iptables commands. It is meant to be a guideline only, since any firewall is specific to the services the host offers, and the services the administrator permits local users to use.

NOTE: As is, the script only allows ident (port 113) requests, ftp only works in PASV mode from the client side, IRC DCC sends and chats initiated from behind the firewall are blocked, but incoming DCC requests work (hint: to DCC chat from behind this firewall, use /ctcp nick chat). ICQ is also broken in a few ways, although you can send messages.

This is a self contained script, and it assumes kernel support, and modules.
