With wg-quick, the config file name will be used as interface name, but our Config Generator builds too complex names. So, rename the .conf file you want to use to a friendly interface name, e.g.

mv /Users/myuser/Downloads/AirVPN_BE-Brussels_Columba_UDP-1637.conf /Users/myuser/Downloads/wg.conf

To start tunnel

sudo wg-quick up /Users/myuser/Downloads/wg.conf

Use a full path to qualify your .conf.

To stop tunnel

sudo wg-quick down /Users/myuser/Downloads/wg.conf

Use an absolute path to qualify your .conf.
