Start/stop interface
wg-quick up wg0
wg-quick down wg0

Start/stop service
$ sudo systemctl stop [email protected]
$ sudo systemctl start [email protected]

Instead of having to modify the file for every client you want to add to the
server you could also use the wg tool instead:

# add peer
wg set wg0 peer allowed-ips 10.0.0.x/32

# verify connection
wg

# save to config
wg-quick save wg0
