Can I configure the agent such that it registers with the server with an address
that can be reached by the server when using an SSH tunnel to connect to the server (like the SSH DISPLAY environment variable for X forwarding?)
The scenario is that there's an agent installed on my laptop and I am connecting
to our server via an SSH tunnel. I can port forward the outgoing connection OK,
but the agent registers with a particular network interface address which of course
is not reachable by the server. If I could configure the agent to register with an
address like localhost:agentPort I can configure SSH to forward connections back
to my laptop...
