+Nounours (my main router) has a number of tunnels:

+===== 1 - Tunnels to OZ7SAT =====
+Two tunnels exist between Nounours and Amsat (The OZ7SAT group's SatNOGS groundstation at Amanger):
   - The main tunnel, the purpose of which is to enable management access to AMSAT
-  - The backup tunnel, which primarily exists because the main tunnel that uses Wireguard from time to time stops working. I can the use the backup tunnel to access Amsat and remedy the situation.
