Does (from work to home) "telnet home 443" print the SSH banner
Are there any logs about broken connections at home? Maybe there
is something bad about MTU mismatches, etc.?
Hint: you can set up IPFILTER with a "custom" config via files
and "log" all packets from your work's IP address(es), then go
review the ipmon logs.

Beside SSH, take a look at OpenVPN - they had some method of
co-existing with an HTTPS server. Possibly, your work's firewall
is smart enough to probe the port you requested and find out that
there is no HTTP(S) on it, so it denies the connection. If your
home's port 443 does serve HTTPS, even if just an Apache Welcome
page, this test would likely pass.
If this works, you can fire up an OpenVPN client connection from
work to home, and use SSH with minimal encryption inside this
tunnel. This does add overhead, but should work.
