IP Masquerading acts as a "one-way trap" for IP connections. All outgoing connections originating from your internal network are allowed. All incoming connections originating from the Internet are denied. This machine is meant to be a single point of attack for your network. It will prevent your internal machines from being directly attacked but could be compromised itself as new exploits are discovered. For improved security, regular software upgrades to the machine are recommended.

The Firewall module allows you fine-grain control over all IP traffic. For example, if you don't want someone to use chat programs on the Internet, the port chat runs on could be blocked. Similarly, if you have an internal web server that you want the world to get to, with the firewall module, you can allow web traffic into that machine while still protecting the rest of your network. This type of firewall is a step up in security from just IP Masquerading because it prevents arbitrary connections from coming into the server and provides logging of attempted attacks.
