I.P Help

[Me=Mc-Noob]

I was wondering if there is a way that I can transmit off as a different Ip address then what I actually have. EXAMPLE:
My IP: aaa.aa.aa.aa What everyone thinks I have: bb.bbb.bb.bb

Can any one give me a detailed tutorial? I also heard something about proxy program. Does that work that way. Im also behind a router and have been having problems with several programs because I need to "Port Forward." Will my router effect my I.P?

Most likely your router will send you out as a certain IP no matter what you do on your computer. You will probably have to set the router up with a new IP if you want to do something like you are talking about.
