NetDefender is a Free Firewall with source code, which can be downloaded along with firewall executables. Netdefender works on windows 2000 and windows XP.
For More Information please check : Netdefender DetailsRequirements :
1. Netdefender can only run on an OS higher than windows 2000 (i.e. Win 2000, Win Xp I hope Vista would not break anything)
2. User must has admin rights (i.e. must be member of administrator group ) on the system.
3. Default Firewall of windows Xp must not be running . In windows Xp with service pack 2 Default firewall is always running. So you need to stop it before running the Netdefender.Screen Shots :Main Screen :Add Rule Dialog :Port Scanner :
