Do you mean Draytek Vigor 2910? *If yes, read this: http://www.draytek.co.uk/support/kb_vigor_portforwarding.html You want to forward TCP port 25565 in and out to the computer that is hosting the minecraft server. To get the IP of the computer hosting the minecraft server, click the airport button in the bar at the top of your screen and go to network preferences. For me, in network preferences, it says: Code: Wi-Fi is connected to CiscoCatalyst and has the IP address 172.16.1.6. The 172.16.1.6 part for me is the IP address of my computer, on my network. For you, this may say "10.0.0.something" or "192.168.1.something" The IP address you get from the network preferences screen is the one you must enter as the 'Private IP' in the port forwarding settings. Please go to your mac's network preferences (The big long bar at the top of your screen, towards the right-hand side of it ) and get your current IP address from there.
