razmoket_ I know this is a little old now, but have you tried using Hamachi or Radmin VPN to join eachother over LAN? I'm pretty sure it worked for me to create a Hamachi network, get my friend to join my network, then get my friend to open plutonium console (by pressing ~) and type in "connect x.x.x.x", with x.x.x.x being my Hamachi IP from the network.
