I have a network with few devices with IP addresses 192.168.1.1, 192.168.1.2, 192.168.1.3.
I have access to devices 192.168.1.2 and 192.168.1.3 (both linux).
A program is running on 192.168.1.2 and connecting to 192.168.1.1 using udp socket, I cannot modify that program.
How can I make the program on 192.168.1.2 to connect to 192.168.1.3 instead? I can run anything on 192.168.1.2 even on root permissions (hopefully something that can change IP addresses) and before the program is run. A link to API guide on this will be helpful (C#/C++/Perl), although a working program will be better.

You can use iptables on x.x.x.2 to redirect to x.x.x.3 instead of x.1. Post your q. on serverfault or superuser for details. It has nothing to do with programming.
