we are building a single ESXi host based NSX-T 3.0 deployment.
we have two issues :
1. tunnel between the Host TEP and Edge transport node TEP is down.
2. As shown in the below topology diagram, from the Application server running in the segment1, we can ping the 10.204.253.18 IP, but unable to ping the external Tier-0 interface IP 10.204.253.191.
