I saw a forum post from last year, but I am curious how the MP is right now. Are there any servers up at all, or do I need a LAN VPN type program to connect two copies of the game?

Closed servers held up by Ascaron are down yes but you can use the open server function (you import your single or offline LAN characters). You can use a VPN as well but that is more of a convenience or for latency issues.
How exactly do you get on the Open Servers? I believe I have all the information right in my settings file, but I still can't seem to connect!
I don't recall you have to connect to the open servers, it's just a local gateway to connect to other players. However, the usual culprit is either a firewall (software) or a router (hardware). If you're sure your ports are open I'm not entirely sure. I could try it myself.

Edit: I seem to have issues myself both connection and apparently my Undeworld key is invalid.

Anyway, there's a possibility open servers were connected to Ascaron's servers but I remember reading something on the official forum about being able to if you connected to a back up server or perhaps an unofficial run by some fans.

I would recommend running a VPN (Tunngle, GameRanger, Hamachi) and then playing via LAN. This requires organisation so you can't really play with randoms.

This seems to be a good page:
