Encryption for L3 on asymmetric traffic in FGSP

In scenarios where asymmetric routing between FGSP members occurs, the return traffic can be encrypted and routed back to the session owner on Layer 3 (L3).

To encrypt L3 traffic in FGSP:

1. Run the following on both FortiGates:

   config system standalone-cluster 
       set encryption enable
       set psksecret xxxxxxxxx
   end
