Hi There.

I'm struggling with Networking on Dosbox inside Win 98.

What I want to achieve: Running Win95/98 based Games inside a PORTABLE Dosbox with Multiplayer
What I got so far: Win98 running with SLIRP and Port-Forwarding.

PCAP is not an option, since its not really portable and doesnt support WIFI Adapters.

So, I'm currently trying to get Airline Tycoon Multiplayer to work.
I know it can be done under Win11 but thats not the challenge here.

With SLIRP it failes, because it relies on DirectPlay which, whyever, always uses a random Source Port between 40000-70000...
I cant forward that many ports (Dosbox gets extremely slow).

So... TCP/IP seems to be no option for that game. Without some kind of tunneling or somthing.

2 Questions:

1. Is there a possibility to Tunnel 2 Dosbox Instances over SLIRP / TCP/IP with Port-Forwarding?
Maybe some kind of VPN Thingy...

2. Is it possible to use the Build-In IPXTunnel with Windows98 as guest?
It works well on DOS, but doesnt work at all on Win98.

3. Any other solution?

Edit: Serial Connection works for 2 Players, but I need support for 3+ Players.

Greetings,
