I'm setting up a Dude server to monitor all the Mikrotik devices in the network, it works really great and I even get Telegram notifications.
Next challenge, if possible, is that I want The Dude to monitor my three outgoing ADSL lines. The dude is installed on a local Mikrotik device within the network. The local network is connected through one Sonicwall device via 3 ADSL lines (load balancing) to the internet. How can The Dude monitor the status of those three ADSL lines. I want to get a notification if one of the ADSL lines goes down.
The ADSL modems do not have a pingable IP address. I tried to ping the public IP address but that doesn't seem to work either.
Any suggestions? Thanks.
