At work I'm behind a pretty strict firewall, everything is closed
inbound, and I can only use port 21 and 80 outbound. I would like to
connect to my home server by means of SSH. My ISP doesn't offer a proxy
server, and any attempts at using public proxies :80 have failed,
usually with a 403 forbidden. Yes, 8080 is also closed.

Then talk to your System Administrator and have the required permissions
from your office's director. The rules that have been put in place are
mostly to protect the LAN environment, trying to bypass them would be
enough to be fired immediately, depending on the 'fair use' policy
in your office.

Thanks for the quick reply, I asked my boss and got permission. Then I
asked the admin who will discuss it with my boss. I don't think I would
get fired for trying other methods though; any ideas?

Your employer doesn't seem to want you using anything but FTP or HTTP.
If you are willing to risk your job, you can setup ssh on your home
machine to listen on port 21 or 80 or 443 (You didn't mention 443, but
secure web pages use that port). If your work machine doesn't have an
ssh client, you're wasting your time. Be aware that your bosses might
monitor the IP addresses to which you connect.

Where will it all end? Probably somewhere near where it all began.

Indeed, 443 is open. However I'm using all these ports for other
purposes on my server. As it's Friday, 3pm, I think I'll wait 'till
next week before investigating some tunneling option. Or perhaps the
port will be opened before too long. Thanks sofar.
