This will enable an outside user to ssh (or vnc/etc) to a machine behind a restrictive firewall as long as you can ssh (perhaps over http proxy even) to a remote public machine.
#private - the machine behind the firewall
#public - the public machine
#outsider - the person that requires access to #private
from #private
[1] private# ssh -R 9000:localhost:22 user@public.domain.com
from #public
[2] outsider# ssh user@public.domain.com
now in that ssh session, #outsider can ssh through the reverse proxy you set up in [1]
[3] user@public# ssh -p 9000 root@localhost
#outsider now has access to #private
