+The login and world servers will attempt to bind to MB_BIND_ADDR when starting.  By default this is configured to eth0.
+
+When clicking 'enter world' the client will attempt to contact the game using MB_EXTERNAL_ADDR.  By default this is configured using a call to whatismyip.
+
+**The external ip must be reachable from outside your network.**  Some admins will need port forwarding.  Some admins will need to manually set the external address.
+
+Magicbane when booting logs to the console the addresses and ports it is listening on.  Search for "Initializing Network" within the console logs.
