If I am wrong what I am asking Plz do correct me

1. How can I change The Source IP in the IP Header

Answers:
1. Don't do it (won't work on XPsp2) ... Many routers have protection against IP spoofing too.
2. Source address in the HTTP header, are you sure? (I've never seen any)

If it is your own web application, disable these check during your tests.

If you must work from different source addresses, go via some free web proxy. I think there are many such proxies out there-- 'cause in some contries it is forbidden to browse certain content/URLs.


Good luck.

PS. You may also be able to change your WAN/LAN IP adress (it is easy on a LAN)... If you're sitting on a DHCP WAN address provided by your ISP, try changing your PC's or router's MAC address and then renew the IP (ipconfig /renew). Your PC's MAC address can be changed (in Windows) via the registry (search on Google on how to do that). It's more tricky on a firewall/router, but many of these support "MAC cloning"... which means that it will copy your PC's MAC adress.

it would work on sp2 with patched tcpip.sys
