RSync + SSH tunneling through firewall

[Stefaan Lhermitte]

I tried to connect the tunnel with another port number. When I use port 
number 22 instead of 873 I can telnet to C from B.
When I telnet I get  "SSH-1.99-OpenSSH_3.9p1."

Subsequently I ran: ssh -v -L 22:C-computer:22 myname at B-computer

When I run now the rsync command:
rsync -v /cygdrive/d/folder/ 127.0.0.1::cygdrive/folder
I get the error: "failed to connect to 127.0.0.1. Connection refused."

When I run:
rsync -v --port=22 /cygdrive/d/folder/ 127.0.0.1::cygdrive/folder
I get the error "server sent SSH-1.99-OpenSSH_3.9p1 rather than greeting"

I assume it is a problem associated with the telnet command. Can anyone 
help?

Kind regards;
Stef
