As stated below, the -L option might work. Below are general ssh
forwarding instructions, maybe you can adapt to your situation:
ssh -l user -v -L2001:machine_behind_firewall_ip:22 firewall_machine
In a different shell:
ssh -l user -p 2001 localhost
You should be in the "machine_behind_firewall_ip" You can also send
commands:
ssh -l user -p 2001 localhost ls
Note: make sure nothing is using the local port you decide to use.
