yup, i played on tunngle with many players, its great. But you can connect to non oficial server too. 217.123.174.227
Try direct IP with no Tungle or Hamachi, I find those programs are just more of the same in a different format, you have to do a lot more work to set them up vs put an IP in and play for client and for the host set a port forward on router/modem if needed, a lot of the time you don't even need to do that.
