I'm using a WinXP PC as my router/firewall. I've been trying to open the ports for my Ubuntu/ISPconfig Webserver but it doesn't work. I've also tried to find software that I can forward ports or set a DMZ zone. The main reason I use a WinXP machine is because I want to have a separate firewall for all my Win PCs and just have the server set as DMZ with it's own firewall. Is this even possible with the windows Internet Connection Firewall? Or is there software available for windows which does the same thing?
