I am using the same method as described in the above link by turning on the Internet connection sharing (ICS) to the TAP interface in my windows xp (OpenVPN server). It works fine.
Recently, I have upgraded my Internet to 200M and I want to utilize all bandwidth without upgrading my wifi router. Therefore, I am planning to plug the 200M WAN directly to my windows xp (OpenVPN server) and then share it to other computers in my home via another LAN interface. This means that I will using my windows xp as a router.
Is there any solution to replace the "ICS to TAP interface", so that I could release the ICS to another LAN interface? Any other suggestions are welcomed, thanks.
