This page is for configuring networking options for the SSH server. Some of the less obvious options are :

Idle timeout
  If this is set and there has been nothing sent by the client or server during the period set, the client will be disconnected.

Disconnect if client has crashed?
  If set to Yes, the SSH server will periodically check to see if the client is still alive. If not (because of a network error or client machine crash) it will be disconnected.

Allow TCP forwarding?
  If this option is set, users can tunnel TCP connections from client machines to machines on the server's network, and also allow connections back from the server to machines on the client network.
