We have a number of Watchguard XTMs in production that provide WAN connectivity via Branch Office VPN. These are also configured with failover connections as well. Although NPM appears to pick up the physical interfaces of the Watchguard devices and also their VLANs, it doesn't appear to pick up the VPN tunnels.
Is NPM able to recognise VPNs on Watchguards as a network interface object, and if so, how should it be configured so that it does.
If NPM isn't able to recognise these in this way, how do you configure it so that it's able to display throughput data and also alert on failure or backup failover?
