SSH port-forward Router Telnet sessions

Hi all,

 I have a work Ubuntu server running GNS3 for CCIE R&S study and a Mac at home. I can use my local Mac terminal program at home to telnet to each router console at work through an SSH tunnel with ssh local port forwarding:

ssh -L 2001:localhost:2001 <user>@<work-pc>

then

telnet localhost 2001

But with 10 or so routers running its not practical to create 10 ssh sessions. I am sure this can be done with a single ssh tunnel. I have tried to use ssh dynamic port forwarding and socks proxy but no luck yet. Can anyone explain how it can be done?

Kind Regards,

Nigel
