>It is recommended that you change the external port only via the docker run command not within [magicbane.conf](http://repo.magicbane.com/MagicBane/Server/wiki/magicbane.conf). Docker will automatically bridge traffic to the correct interal port. MagicBox uses three ports. 5000 is used optionally for a debugger or profiler. 6000 is used for the login server. 8000 is used for the world server. If behind a NAT/router the user must open these ports on his router or configure a DMZ.
