Hi, Don't take this as conclusive (as I gave your post only a quick read) but:
<<Is there more to it that just changing addresses?>> What you're trying to do is called NAT (Network Address Translation) and at the very least, you've got to recompute the IP header checksum. I recommend you pick up Doug Comer's book on networking, "Internetworking With TCP/IP Volume 1: Principles Protocols, and Architecture, 4th edition, 2000. ISBN 0-13-018380-6" It's usually available used on Amazon for under $20. Cheers, Rob ================================================================== This is the WinPcap users list.
