VNC

The other day I was away from my Mac and thought I'd try out VNC to see if it worked; I left my Mac on and realised after a few attempts that the 192.168.1.64 wouldn't work away from my router network.
What address(s) do I use for away from home viewing?

iMac 20" 2.66 GHz core 2 duo 320GB, Mac OS X (10.5.5), 8GB Original iPhone

Hi,

If you are using the built in vnc server on your mac 'screen sharing' then you need to setup port forwarding from your router to the IP address of your mac.

by default screen sharing using tcp port 5900

once that is setup to access your mac away from home you would use the WAN or Public IP address of your home internet connection as the vnc server address.

Great; how do you set up port forwarding? (my router is a wireless BT Home Hub) and how do I find out my WAN?

I do not know about the BT Home Hub, but if you do a Google search for "BT Home Hub port forward" you will find instructions.

As for finding out your IP address, you can use something like <http://whatismyip.com>

Another approach is to go to no-ip.com or dyndns.org and get a free Dynamic DNS name. You then run a dynamic DNS client on your Mac that will keep the Dynamic DNS name updated with whatever your ISP sets your IP address to. dynamic DNS clients are available from no-ip.com and dyndns.org.

no once your ichat name is my buddy list, I right click on you and send a request to sreenshare, a message on your mac comes up saying tim haigh wishes to share your screen. you click yes.

then i see your screen on my desktop and we have an audio connection so we can talk to each other.

after its done you can cancel the screenshare and we are done. Screen sharing is great and is totally secure as no one can take over your computer unless you permit it.

The time capsule does not have a integrated modem so in order to use that as your router you would have to setup your BT home hub as a bridge. I am unsure if this is supported with the BT firmware on that box.

The usual way to use a time capsule with another router is to setup the time capsule up as an access point only. It does not do any routing.

I have setup port forwarding on BT home hubs many times and its not a problem using the FAQ i posted earlier in this thread. the BT home hub is not the best router in the world however port forwarding does work.

do you have a dot mac account?
