Hi,
I have been sifting through the forums but cannot find a definitive answer to my question.
Scenario:
I have a CHR running dude server. All my routers I want to monitor connect to the CHR via a L2TP/IPSEC VPN. The addresses are assigned to the vpn clients from a pool. The dude will auto discover the routers and monitor them beautifully. The only problem is some routers have flaky uplinks and the vpn can drop ever few days. When this happens the router will re-connect to the vpn but it will be assigned a different IP address from the pool. When this happens, Dude will auto-discover the new IP address but the old IP address will remain and showing offline.
Question:
How can I monitor routers with IPs that change? This VPN is purely for monitoring purposes so I don't care what the IP address is but I do care about the device name and weather it is online or not. I'm not using dynamic DNS or anything of the sorts.
I'm already pulling the router identity via SNMP which will always be unique because it includes the RB serial number. perhaps that could be useful?
TIA <3
