Sounds very complicated, and it is not very secure.  Have you considered
using a tunnel, either SSH or Zebedee?  

I personally use OpenSSH (the 'lexa' package), although if you're new to all
this, Zebedee may be easier.  All software is free (at least as in 'beer',
if not in 'speech').  I have the following setup: XP machine at home that
runs OpenSSH for Windows, and a firewall/router configured to allow incoming
traffic on port 22 to that machine.  I use Putty (a free SSH client, no
installer) to connect to the OpenSSH server and to open several tunnels:
forward localhost's 5900 and 5800 ports to my home machine.  Then in my
browser I simply type http://localhost:5800, or in the VNC viewer
'localhost'.  Voila, that's it, two firewalls, one proxy and one router
bypassed easily and securely.

The advantages to using a tunnel are many:
- will bypass most firewalls (AFAIK - you have to start looking at packet
contents to atop this)
- only need to open one port on the firewall/router
- data compression between SSH client and server (so faster, in theory at
least)
- facilitates file transfer (SFTP/SCP for OpenSSH, I believe that Zebedee
has something similar but easier)

There are two slight disadvantages:
- need to install an SSH or Zebedee server on your machine at home
- need to configure Putty (at work) to forward ports and use your Proxy

It's really not that difficult - just one thing to install (a Zebedee or SSH
server) and one thing to configure (Putty or whatever client you're using)
and as the saying goes, if I managed to do it, anybody should be :).
