[ILUG] How do I make the first ssh connection?

:>If I try from work, I suspect port 22 isn't allowed out in any case.  I
:>get a "connection refused" error that way.  I have port 21 forwarded to
:>port 22 through the home firewall and am attempting to connect via port 21
:>through the work firewall (I'm allowed ftp access).  I wonder are there
:>some issues with the ftp protocol (which is expected to use port 21) and
:>the firewall rules that would be normally used for ftp.  The work firewall
:>is an NT NAT forewall over which I have no control.  Alternatively, are
:>there special rules necessary for ssh that would be applied to port 22?
:>For example, my port 22 rule includes mention of
:>$SSH_REMOTE_PORTS="513:65535" though I wouldn't think the lack of such
:>stuff would make too much difference.  I had port 80 forwarded to port 22
:>also but an ssh -p80 would return "connection established" and then hang
:>before any ssh stuff happened.

:>Still stumped.  Anyone got an account on redbrick they could loan me to
:>use for testing?  I could try to connect from there and at least get my
:>end figured out.

You won't be ssh'ing out of RedBrick to anywhere ;) 
All blocked.
