Run the VPN Diagnostic Report
From the Diagnostics page, you can run the VPN Diagnostic Report to see configuration and status information for a VPN gateway and the associated branch office VPN tunnels. When you run the report, the Firebox temporarily increases the log level for the selected gateway. The completed report shows the gateway and tunnel configuration, as well as information about the status of any active tunnels for the selected gateway.
You can also run the VPN Diagnostic Report from the VPN Statistics page. For information about how to run the report from the VPN Statistics page, see Run VPN Statistical Reports.
To run the VPN Diagnostic Report from the Diagnostics page:
- Select System Status > Diagnostics.
The Diagnostics page appears with the Diagnostics File tab selected.
- Select the VPN tab.
The VPN diagnostic report options appear.
- From the Gateway drop-down list, select a VPN gateway.
- In the Duration text box, type the number of seconds to run the VPN Diagnostic Report.
- Click Start Report.
The diagnostic task starts.
The Firebox collects log messages for the duration you specified. When the task is completed, details about the gateway and tunnel configuration and information about the status of any active tunnels for the selected gateway appear in the Results section. The log level is then returned to the previously set level.

VPN Diagnostic Report Details
The VPN Diagnostic Report includes these sections:
This is the complete report summary and can include information about actions you can take to resolve any issues identified by the report. For each tunnel route, the report shows whether the tunnel route was established, whether traffic was detected after the report started, and error messages related to the tunnel. Some error messages include information about what you can do to correct a problem with the VPN tunnel.
This is a summary of the gateway configuration and each configured gateway endpoint.
This is a summary of the tunnel configuration for all tunnels that use the selected gateway. This includes both active and inactive tunnels.
Run-time Info (bvpn routes)
This section appears only when you run the diagnostic report for a branch office VPN virtual interface. It includes the static and dynamic routes that use the BOVPN virtual interface and the metric for each route.
Run-time Info (gateway IKE_SA)
The status of the IKE (Phase 1) security association for the gateway.
Run-time Info (tunnel IPSEC_SA)
The status of the IPSec tunnel (Phase 2) security association for active tunnels that use the gateway.
Run-time Info (tunnel IPSec_SP)
The status of the IPSec tunnel (Phase 2) security policy for active tunnels that use the gateway.

The status of the address pairs for each tunnel. This section does not appear when you run the report for a branch office VPN virtual interface or for a BOVPN on a cloud-managed Firebox.
Policy checker result
The policies that manage inbound and outbound traffic for each tunnel route.
If tunnel negotiation occurs while the Diagnostic Report runs, the tunnel negotiation log messages appear in this section. If the remote device attempts to negotiate or rekey the tunnel while the report runs, the log messages that appear in this section include more informative details.
