I want to modify certain outgoing packets from my Windows XP box. What would be the easiest way to do this?
(e.g. if the dest.port == 2500, then slap on another TCP/IP header with dest.port==25 and dest.ip==11.22.33.44 -- encapsulation or IP tunneling, I guess)
I tried finding a program or build-in Windows function that would do this, but had no luck. The closest thing I found involved writing my own driver or something, and the site I found assumed I know way more than I know right now, so that didn't work out.
