We have 24 Cisco ASA connected in a mesh using IPsec VPN tunnels. From our hub location we have Sitescope monitoring each firewall and VPN tunnel to that firewall by ping its inside interface. That works great from the hub location and is more of a hub and spoke model but this is a meshed VPN and I need to monitor the other sites. I don't want to put Sitescope servers in all locations nor would I do that. What are people using these days to monitor thier VPN tunnels? How do you know when a location can't talk to another location? Looking to be proactive here and not wait for an office to notify me that a tunnel is down.
Thanks for the help.
