Service Port For Telnet, SSH, FTP, HTTP or HTTPS services, you may change the default service
port by typing the new port number in the Server Port field. If you change the default
port number then you will have to let people (who wish to use the service) know the new
port number for that service.
Timeout Type how many minutes (between 1 and 255) a management session (via the web
configurator) can be left idle before the session times out. After it times out you have to
log in with your password again. Very long idle timeouts may have security risks.
