Thanks Ray once again for your very prompt response. I did go looking for the external IP and found it and tried it but it does not work so I assume my port forwarding is the problem. It is an airport extreme V7.6.4 and I feel like I have done all of the right things but it does not work. I have of course looked up all sorts of sites but none of them seem to duplicate the menu structure I have on my airport. I also read a post that said there was a problem with the upgrade ( 7.6.4) so it could be a bug. I will keep looking until I crack it. Thanks for your help.
