Client remote port forwarding?

[jurex]

Hey guys, is it possible to implement remote/reverse port forwarding from the client side? Something similar as -R switch used in the ssh command: ssh -R 9090:localhost:8080 some.remoteserver.com

I'm currently using swift-nio to run a local web server + websocket in the iOS application, and I would like to expose it using the remote ssh server without any additional port forwarding configured on the router. Is it something like this even possible using swift-nio? Thanks!

Yes, this supports reverse port forwarding using the forwardedTCPIP channel type and the TCPForwardingRequest global request.

There is currently no demo for this, so putting it together will require some fairly deep understanding of how SSH implements this functionality.

Awesome, thanks for quick reply! At least I know it's possible now, so I can start with basic experiments.
