ip and port forwarding in windown 2003

[jindalarpan]

Hi
am i having a acquirement of forward the ip address and port number to some different ip from windows machine. I know there could be many ways through which t can be done at network layer but that requires too much of changes. is it possible to do the same in windows.

Issue is like:
if i am running windows on server with ip (10.10.10.10). i want if someone or any application from this windows server try to connect to 10.10.20.30 on port 1234 it should go to 10.10.30.40 on port 1234. with out giving any issue to application.

How to set this up?
I have done similar thing in Linux using IPTABLES but IPTABLES for Windows is not available so looking for the way which could help me in setting up the same in windows.

Thanks in advance.
:)

Well its a complicated process with either using RAS (or ISA) with IP filtering at local network (or using a router obviously).
