Here is the setup:
Site 1 and 2 are Organizations inside the same vCloud Director 9.1 deployment.
Site 1 - has some vApps using vApp networks and 1:1 NATs to an "External Network". This external happens to be something like a 10.10.x.y/24 network.
Site 2 - uses the Catalog Sync feature to pull the vApps across the wire to local storage. The Org vDC has a direct connect "External Network" that the NAT should use, but this is some 10.50.x.y/24 network.
When a user deploys the vApp in Site 2, the NAT doesn't seem to automatically pick the local external network. I vaguely recall this being due to a network mismatch, but can't remember.
Just trying to see if there is a way for users to just login, add something from catalog, and click NEXT (until finish). Very little interaction for sake of drop downs.
