User level NATing

Hi,
Is there anyway i can do a user level NATing of IP packets send by
programs running with user privileges.


for example if john is the user and
john has a program which does user level NATing,then can john modify
the IP packets sent by his browser for example???

Thanx in advance
Manu

creating IP packets requires root privileges, sorry!

No, NATting changes IP and TCP header, for this you need root
privileges. May be you should explain what you want to achieve
with the "user level" NATting.
