Instructions
Add ssh keys for the services you want to proxy to.
Then start ssh client (example of forwarding my-cool-service.handle.example.com.fedproxy.com to port 8080 locally):
ssh -NnT -p 2222 \
-o UserKnownHostsFile=/dev/null \
-o StrictHostKeyChecking=no \
-o PasswordAuthentication=no \
-R my-cool-service:80:127.0.0.1:8080 \
handle.example.com@fedproxy.com
