I feel that I’ve done everything right. I’ve created a section in the port forwarding section that forwards all incoming port 22-29 connections to port 22 and my servers ip. When I try to connect from an outside network as USERNAME@MY PUBLIC IP it just times out.
I think they are asking how to configure Port forwarding on their border router/firewall for incoming SSH connections from elsewhere on the Internet.
Not how to transport other protocols over a working SSH connection.
Hard to say without proper info
