Creating a game over a local network

[Dune2100]

Hello. Is it possible to add a separate item to the game in the multiplayer game menu in order to play only over an IPv4 LAN?
The main problem is that it is not possible to create a server over IPv6.

All attempts to create a host are unsuccessful. Even when using Hamachi, the game settings determine the connection only through a shared server and port 2100.

I'm using a translator, I'm sorry.
