George:
Heya. I think Matthew's and William's suggestion was spot-on:
you want to setup your firewall/router to forward the ports like this:
> ExternalIP:5900 -> Internal1:5900
> ExternalIP:5901 -> Internal2:5900
> ExternalIP:5902 -> Internal3:5900
Then you only need to change the display number you're using
on the client side to be able to reach all of your machines.
One possible downside: some low-end firewall/routers won't
allow you to remap a port-number like this (ie, sending 5902 external
to an 5900 internal). Most will nowadays, but I still comes across
networks where the appliance doesn't allow this. Another possible
hiccup is that if your internal network is using DHCP, your static
mappings in the router might not reach the machines your shooting for
if those IP address change. Again, with most of the newest router
appliances, DHCP is handled smarter than this so it won't be a problem.
Another alternative you might want to try is Kaboodle. The
latest release version is 0.95, but I've got 0.99 working and it's
fairly stable if you'd like to alpha-site it. The idea with Kaboodle
is that it's a "VNC Gateway" and it uses only two TCP ports. So
if you've got Kaboodle running on PC1 on LAN1 and Kaboodle running
on PC2 on LAN2, you can VNC from PC1 to any of the VNC servers
which are a peer with PC2. Kaboodle uses Zebedee to create these
connections, so it has the added benefit of being a cryptographically
secured connection. Yes, you could use Zebedee (or SSH) on its own
to achieve the same effect, but I tried to take away some of the
hassle of getting all of the binaries playing together nicely.
If you're interested in giving the pre-release version a whirl,
please let me know and I'll put a copy up on my server.
cheers,
Scott
