Thread: Using windows xp as a router

• Just install an additional network card in the box and after that configure the registry setting below and your XP box becomes able to route IP packets from one interface to another.
• Open Regedit and browse:
• HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Tcpip\Parameters
• Find the following registry value:
IPEnableRouter
• Set this value to 1 to enable IP routing on the box.
• After doing this, restart the computer.
• You can also require disabling Windows Firewall on the computer.

that is good to know, thanks for posting
