    Listen to outbound IPs

    My setup is as following (windows XP). I have an emulator that tries to connect to a specific IP of a DNS server. It basically starts and sends a UDP packet on port 53 on the specified IP (cannot change).
    I have then another fake DNS server that listens to a configurable IP and resolves the DNS query. My issue is that practically the only way for it to work is if the emulator tries to connect to the localhost. What I would like is somehow the default gateway to return back to the localhost. Or just route back a specific IP to the localhost.
    I tried first "route" command but it cannot route to the localhost. Using virtualbox would theoretically work but it is to heavy just to do what I want.

    Any ideas? Purpose is to test without needed another machine.

    It depends on the facilities of your router and "OS", but you may be able to ask your router to do this for you.

    Using a router would be the preferred approach.

    That said, this is possible within almost every "OS" including "Windows XP".

    Thanks, that worked great! Not the smoothest solution as you I cannot actually keep a static IP (IT guys will hate me) but I can switch back and forward and do my testing just fine
