Need to create a software router

[duhh]

I am wondering if anyone has a solution to help me out.

Under windows (An I have no controll over the computers attached to the network, or the network itself, so please do not suggest an alternate os or throwing another device on) I would like to create something along the lines of a "virtual router".

I would like to connect to some local resources, but setup my application like I was at another location. Basically, I would like to direct my app to the IP which would be used externally, but then have my computer catch trafic headed to IP xxx.xxx.xxx.xxx and redirect it to yyy.yyy.yyy.yyy. I know this could be accomplished by screwing with the hosts file, if I were using hostnames, but I cant use hostnames.

Any ideas on how to do this ?

I dont think this really applies, all I really need to be able to do is have a software nat table. I dont really see how I can carry that out on winroute with just one pc.
