On a connection it can be specified to use an existing VPN. However, the selectable sessions are only main connections, and not one of their sub-connections.
Context for a mysqldb:
- main connection: host
- sub connection: port forward to connect on localhost (should only be active when needed)
- sub connection: other connection that requires above subconnection to connect
- sub connection: yet other connection that requires first subconnection to connect
- sub connect: ssh shell, does not require the port forward
I have entered a feature request to list the VPN available as sub connection of the entry.
Sorry about the delay. This will be available in the next version of RDM (not 126.96.36.199 but the one after that).
