I was very happy to see someone actually get this to work.  One question
though.  In step 2, you state you use the viewer.  Are you referring to the
Java "web" viewer or the standard viewer?

When I type in "<ip address>:-5879" into the standard VNC Viewer, I get the
error "Invalid Protocol" right away.  If I type it into a web browser, the
title bar area reads "invalid syntax error" and I get "Page cannot be
displayed".

Thanks,
Nick

Hi All,
           Thanks a bunch for the help!  I now have VNC working properly!
I
actually got it working on port 21 & 23 (-5879 and -5877) instead of port
80.  Port 80 might work, but I haven't tried it.  I'm thinking it won't
b/c wouldn't it have to go through the proxy on port 80?  I might try this
tomorrow.
        Anyway, here's what I had to do (note, this was also sent to some
friends so ignore the details you already know):
1.  Copy and paste "-5879" into the display number for the server.  Close,
then restart the server and a weird, long number will display for some
reason.  It's actually running on port 21 though (FTP).
2.  In the viewer enter the name / IP address plus ":-5879".  I'm now able
to connect from work to home despite the firewall / proxy.

You can also use port 23 (telnet) with -5877 (or probably any common port
that isn't blocked).
This *might* work on port 80 too (with -5820), but I haven't tried it
yet.  I'm thinking it won't b/c wouldn't it have to go through the proxy
on port 80?  I might try this tomorrow.

If you're using a router, make sure it's forwarding port 21, 23, or 80 to
the proper machine.
