I'm planning to write a socket firewall for FreeBSD as my university diploma project. By socket firewall, I mean something, that would sit on a router connecting a local network to the internet, and flip all outgoing tcp requests to the only one assigned IP addess. - something that is called masquareding in Linux. Before starting this project, I'd like to make sure that I'm not going to do something, that has already been done - so, please, if anybody knows about a software like this already existing, let me know about it. Also, I'd like to ask for advice how to write this project, so that it can get integrated into the FreeBSD distribution (if it prooves to be usefull and stable). I don't plan to keep its copyright. Thank you for any reply Vlada Mencl
