Some services have been configured to use non-standard port mappings. This is usually done to mitigate the risk of automated port-checking probes.
BitTorrent. This range is used to distribute all bittorrent connections across a wide range of high-number ports. See deluge configuration for more information about what port ranges go to which torrent clients.
Iperf. Iperf defaults to port 5201, which is not a high-number port. Since it is unauthenticated, I use a non-default, high-number port instead.
Git SSH. I use a non-default port for my GitLab SSH server to minimize potential conflicts with other services on the network. It is important to be able to access the GitLab instance over SSH outside the network.
To make configuration changes in the CLI, run configure, make the changes (e.g. set interfaces ethernet eth0 dhcpv6-pd pd 0 interface eth1), then save the changes with commit; save; exit.
