With Evolve play the game as a LAN game and Evolve allows it to be played online with Friends.

You can use Yang or Meltdown or Dukematcher. Included in the Redux Version and free on Steam. You don't use the Redux version you use the Dos-Box version. I only brought up Evolve to try and make this as easy as possible for everyone. Which will be just 1 port that needs to be opened. Check in Evolve's Preferences under Parties Tab and check Use Custom Port when joining Parties instead of UPNP/NAT-PMP.

You can choose to not use UPNP with Evolve and open ports if you'd like.

Evolve's default settings when using UPNP is to prohibit vulnerable protocols from being used in Parties.
