OT: Cygwin - ssh server not allowing port forward

[Bryan O'Neal]

I am running a service on windows I need my clients to connect to. The
service works but traffic is unencrypted. As such I set up cygwin and
sshd. I can ssh in and then telnet on the loclhost (windows sever at
this point) and it works. When I set up the port forward from my
clients it also works. But when I try to push traffic down the tunnel
I get the error. Error is the same on windows and linux clients.
