An administrator recently deployed a Horizon pod with external access using Unified Access Gateway (UAG). While trying to launch VDI from an External network, VDI launches with a black screen and then disconnects. The administrator has validated the port requirement and all other required ports are open. Users are able to connect internally using the connection server URL. While reviewing the UAG logs, the administrator found that the Blast connection is hitting the Connection Server instead of VDI IP.

What should the administrator do to resolve the issue?
