    What are the Pulse/VPN servers using as their default gateway? They should be using the F5 if SNAT is not in use to avoid asymmetric routing.

     

    I would do the following then test:

     

    1. Change the VIP to use SNAT. Test.
    2. If it works, reverse the VIP configuration in step 1 (e.g. no SNAT)
    3. Disable all pool members in POOL_EXAMPLE except for 30.1.1.138
    4. Change the gateway for 30.1.1.138 to 30.1.1.132. Test.

Mea culpa. I added both answers/responses as the second provides a quick procedure on how things should be configured.

 

Many thanks.
