VPN peer not responding or unreachable

This is a real life sample alert from indeni

Description:

Some of the device’s VPN peers are not responding to VPN traffic.

Affected VPN Peers

VPN peer 191.119.141.40 is currently not responding

Manual Remediation Steps:

The VPN peer is not responding to VPN traffic. Please check network connectivity and contact the administrator of the VPN peer to ensure VPN is still enabled.

Note that many VPN peers do not respond to ICMP pings and will only respond to VPN traffic (such as UDP port 500, IP protocol 50, etc.). To test that the VPN peer responds to VPN traffic, use Nmap’s ike-version script.

How does this alert work?

indeni uses device-specific commands and logs to determine if the VPN peer is not responding.
