Best VPN? Hamachi, Teamviewer, Tuungle, or?

Just as the title says. What is the best VPN for old games i guess one that would support IPX as well for really old games like starcraft etc.

I used to use Hamachi version 1.37 or something like that. However it's no longer support and could only hold 5 friends in a "channel".

Teamviewer's VPN doesn't seem to hold a connection open very long. Seems to have random disconnects but that may have been our setup and I've only tested it with Terraria. Not sure if it'd work with other games.

Tuungle was a pipe dream when I looked at it last. It was meant to be the replacement for many classic gaming services like gamespy, mplayer, T.E.N. or Kali

So what's the best right now? Looking into Garena now and tuungle... any suggestions welcome.
