Fair enough, but then I'd have to reach *this* old person new tricks
too. Maybe not such a bad idea, at that...

Moving just a bit further along...

Would I be able to do that using my iG5 with 10.4.11?

Myself, I have a fixed IP from Demon...

It doesn't matter what sort of computer you have.

The remote computer must be configured to allow VNC access (and ping, for
ease of debugging). I've no idea how you do this on a Mac - sorry.

If you have a static IP then you can set up a LAN-LAN VPN using a Vigor
router at each end, with the remote end using Dynamic DNS so the VPN can
connect to it. There may be other routers that will achieve a VPN but I've
no experience with them.

The LAN address at each location must be different. So if you have
192.168.0.0 / 24 then the other site must have something like 192.168.99.0 /
24. What I do is set up the router at each site with an address of the form
192.168.xxx.254 and set its DHCP service to allocate addresses starting at
192.168.xxx.1. I also configure the remote router for management from the
internet (locking this to my own static IP address). That way I can tell
whether the remote user actually has a good internet connection; very useful
when they claim it doesn't work.

I ping the remote router's external address using its DDNS name - this
proves the broadband service is live.

I ping the remote router's internal address - this brings up the VPN.

I ping the remote computer's address. It may be necessary to look at the
DHCP page in the router to establish what this is, but in most cases it
won't change once set up.

Having proved the communications are good, I run VNC to view the remote
screen. The VNC service can be configured to require a password - this is
worth doing. I can also be configured to require acceptance from the local
user - for novice local users this is probably a bad thing.

I imagine it would be possible to use a PC running the VNC viewer to
communicate with the VNC service running on a Mac, and vice versa.
