    Hello ALL ,

    I have a VC cluster connected with  GRE tunnel to a controller in the data center i am routing all the traffic through to the controller IP address

    we found that the response didn't come back to the VC as you can see in the screenshot bellow the output of the 'show vpn tunnels' where the decap packet equal 0 : 


    are there any required configuration in the controller like routing or something to make the response go back

    so this is the case of IAP-VPN using GRE right?
    Have you whitelisted and trusted the IAPs on the Controller?
