What is viprVpnStatsIcmpInDestUnreachs?

This OID records the number of ICMP Destination Unreachable messages received, which indicate that packets failed to reach their intended target on the far network. When this counter rises, it signals that routes are missing, firewalls are blocking traffic, or the remote network is down—all critical troubleshooting signals. A sudden jump from 50 to 500 in an hour would alert you to a major connectivity problem between the VPN endpoints.
