Two admin notes:

1. You keep posting to the gated Partners-only space. If you are seeking community assistance, please post to the public space. I have moved your post to where it belongs. 

2. The info is not enough for providing you with any guidance. Please provide more details: GW versions, configuration, VTI settings, actual situation, troubleshooting steps you did already, observed symptoms, etc.

Is the peer a 3rd party / different vendors gateway?

Note before R81 on the gateway DPD is not the default in this scenario.
