[Wine] Bind app to network interface

[haarp]

Greetings.

I have an old game (Wine98-era) that I want to play with a friend of Hamachi (a VPN). The game only sees the main network interface (eth0) and binds to that. (I can verify that in Wireshark). Attempts to get it to use the Hamachi interface ham0 failed. I've tried changing the localhost line in /etc/hosts to my hamachi ip to no avail. I also tried some Windows app that is supposed to control which network interface other apps bind to, but to no avail.

Is there any way to get this to work?
