How to Intercept connection requests?

Question

Hello, I'm working on an app that needs to intercept when a program tries to connect to an specified IP address and redirects it to another IP.

Is this possible?

I'm using .net for this.

thanks!

Answer 1

Your best bet is to use EasyHook project to hook the connect function.

Answer 2

It might not fit the bill, but you could use the "hosts" file. ("hosts" file will only work for this purpose if the program is not connecting by IP address, but a host name)
