Cannot see connection to Corporate VPN in "Active Sessions"

(Anything related to corporate VPN is actually quite difficult to search for because there are so many topics related to Peplink VPN)

I’m trying to determine the best outbound rules to use in order to route my Corporate VPN (which is IPSec based and has nothing to do with Peplink VPN) tunnel over. Typically I create an outbound rule and then I check active sessions to determine whether my rule was applied as I was expecting. The problem is that I cannot figure out where the VPN tunnel connection is listed within Active Sessions. Perhaps I’m thinking about this incorrectly.

Any help would be appreciated.

I am using a Peplink Balance 20X with 3 ISPs.
