vnc is not http.
If the firewall or route is only allowing http, you are stuck...

You definitly need a dedicated port for vnc trafic. This can be port 80 but 
should not be restricted to the http protocol.

Best idea is to start testing with ports in the default range (5900 trough 5960 
or such).

btw: If the home-users use a vpn connection, best to configure the connection in 
such a way it is also usable the other way around. THen you can just use vnc as 
at the office.
