It might be time to re-think that architecture. For one thing, there
isn't that much security in the VNC architecture (especially with the
free clients).
How about...
* setting up a VPN from each client to your local network? That gets
everything encrypted properly and handles routing correctly.
Depending on quite which VPN client you use, it could either query an
internal DNS server on your local network to resolve hostnames to
local IP addresses, or you could publish (say)
ashley.internal.example.com *publicly* with the correct (RFC 1918)
internal address, which will only be of any use if people can connect
to the local network. (This could be considered a minor security
problem, but it's much less than running unencrypted VNC).
* requiring that everyone use SSH and/or PuTTY to connect, and tunnel
VNC through SSH. You could give them a range of "scripts" / "Saved
Settings" to choose from, which would forward port 5900 on the local
machine to port 5900 on the right machine on the office network.
Hope this helps,
James.
