We can do Monitoring VPN Tunnel using Checkpoint itself We have many tunnels on our checkpoint is being used enterprise wide. I was not found any application or monitoring mechanism for vpn tunnel Monitoring. whenever tunnel goes down, we come to know only if partner or any team complains. So The solution I find this one to monitor vpn tunnels. Here is the way 1) We are using Check Point gateways on both sides of the VPN, the best way to do this is to set Permanent Tunnels in the VPN Community. On the "Tunnel Management" screen of the VPN community we can set up automatic Emails/SNMP Traps for when the tunnel falls down and can't get back up. Once again permanent tunnels only works between Check Point gateways. 2) If the remote firewalls are not Check Point, the best we can do under "Global Properties > Log and Alert" is to set "VPN Configuration & Key Exchange Errors" & "VPN Packet Handling Errors"
