VPN needed for VNC?

I'd like to set up VNC on two macs not on the same network using Chicken of the VNC or similar software. Do I need VPN? I plan to use SSH Tunneling.

I use ssh tunnelling for VNC to Macs without any problem. With Chicken it's mildly annoying to futz with port numbers, but I either just bump the port number up by x and connect to display x, or just forward 5900 to 5900.

The VNC serving is managed by OS X's built in screen sharing.

if they're behind routers (and you're doing NAT, so you don't have real Internet-accessible IPs on the machines themselves), you just need to forward the appropriate ports to the individual machines, or put the machines in the DMZ if the router has this feature. (you can also set up a VPN for this too if you want. forwarding ports might be easier.)

if they've got real IP addresses, then they just need to have the firewall, if any, configured to allow connections on the appropriate ports.

Response by poster: so do I need a VPN and a router that supports that, at the remote end? I thought I don't, but the networking people at my parents' house told them they do.

You don't need VPN if you're using ssh tunneling. Forwarding a port on the router is enough.

ssh tunneling is sufficient. You shouldn't need chicken of the vnc either if you are running 10.5+ as both VNC client and server are built in.

Response by poster: thanks, all, that's what I thought too.

The remote computer I'll want to access is a brand new iMac, so it will have 10.5. I will be using my own, older laptop as the client - will I still need Chicken of the VNC on the laptop?

You will need a VNC client, such as Chicken, or better, Jolly's if you don't have 10.5. Actually, Jolly's is pretty nice even if you do have 10.5 (I use it).
