I managed to make DOSBOX networking successful in Linux using unix utilities socat, slattach, and iptables, and DOS ethersl.com (ethernet over SLIP) utility but I want to somehow do this at the windows end, however I don't have windows installed on any machine. Just linux.

I also want to make a script somehow to set this up.

Reason why I ask is because I'm trying to bring an old game to life so people around the world can play it over their current TCP/IP network without having to change their operating system.

Is there a way this can be done?

I cannot use IPX. I made my own TCP/IP stack which runs over an ethernet frame, so I need an environment like that (that's why in my setup in linux I loaded ethersl.com).
