Can you tell me more about what you mean by “communicate back to the client using that same connection”?
Twingate isn’t bi-directional. Clients can access Resources via Connectors. Resources cannot decide to open up a connection to a Client on their own to send data back. For example: if I have a home server that’s set up as a Resource, I can’t curl files from a macOS that has the client installed.
If that’s what you’re trying to do, you’ll need to either handle everything from the client (like pushing files instead of pulling them) or install the client on the server. I recommend the former, if possible.
