What is the proper way to disconnect from a networked game?

Whenever I try to disconnect from a networked game, it seems like (regardless of whether I am a server or a player) I have an issue. If I disconnect and then try to host a game, it says the port is still in use. If I dc and then try to join a game, I can fetch a host list, but I can't do anything with the host data (join, etc).

I've tried disconnecting with both Network.disconnect and Network.closeConnection(0, false). Is there a better way to do this?

I find that if I am the player that remains after the other has willfully disconnected, I can host and join other games just fine.
