Our ZIA deployment is largely based on IPSEC VPN tunnels from Sonicwall firewalls. We periodically run into issues where the tunnel goes “stale” and stops passing traffic. The tunnel stays up so it doesn’t failover to our secondary VPN tunnel. Disabling and enabling the tunnel resolves the issue. We are looking for a way, preferably in a dashboard view that our helpdesk and NOC can verify that the tunnels between Zscaler and our individual nodes are up. VPN configuration on our side is shown below. Any advice on this our best practices for monitoring would be greatly appreciated.
