TunnelTrace describes a planned local, read-only CLI for diagnosing broken FortiGate IPsec tunnels by checking routing tables and Phase 2 selectors offline.

Landing page captured for the 2026-10-13 issue.

For: Network administrators debugging FortiGate IPsec traffic failures
Worth noticing: It starts with offline parsing of routing tables and Phase 2 selectors, and is still seeking early CLI testers.

Field notes

The proposed workflow centers on offline inspection of routing tables and Phase 2 selectors, with standard-rule checks intended to locate where packets are dropped. The homepage calls the project in development and asks people with FortiGate IPsec debugging experience to share war stories or help test an early CLI version. It does not show a download, so the tool's current availability is unclear.
