However, I cannot do this.
As windows xp does not seem to be flexible enough to allow me to change the host's IP, I need a different solution. Does anyone know of a workaround so that I can use ICS without changing the router's IP? Is there any 3rd party ICS software that would let me do this? I am willing to upgrade to a different operating system (i.e. linux or win2k3server) so that I can share this internet connection with my XBOX.
After brief searching on google I found nothing for winxp and a program called Firestarter for Linux that does internet sharing, but it also seems to use 192.168.0.1 as the host IP. I am uncertain as to whether this is an absolute requirement for the network protocols and whatnot or it is simply a software limitation.
I would appreciate someone's knowledge to point me in the right direction.
