Take a look at 1.3.6.1.4.1.3097 in the ORION MIB database.

There are a number of OIDs for the BoVPN connections... However I have not found a single OID providing a status such as that seen in the device manager. (Active|| Inactive || Expired)

Let me know if you find one.....

EX: From the manual.

VPN Tunnel Status and Subscription Services

The front panel of Firebox System Manager (FSM) includes statistics about current VPN tunnels.

In the Firebox Status area on the right side of the window is a section on BOVPN tunnels. Firebox System Manager shows the current tunnel status and gateway information for each VPN tunnel as well as data sent and received, creation and expiration information, type of authentication and encryption used, and the number of rekeys.

Each BOVPN tunnel is shown in one of three states:

Active

The BOVPN tunnel operates correctly and passes traffic.

Inactive

The BOVPN tunnel has been created, but no tunnel negotiation has occurred. No traffic has been sent through the VPN tunnel.

Expired

The BOVPN tunnel was active, but is no longer active because the tunnel has no traffic or because the link between the gateways was lost.

This information also appears on the Device Status tab in WatchGuard System Manager.
