Thanks for that Sam, but it leaves me a bit confused ... As usual! Our Netgear ADSL modem/router DG384G is connected to the phone line. An Ethernet cable runs from an Ethernet port in the Netgear to the WAN (circle) port in the AE base station. In Airport Utility, it is set to Bridge Mode.
Is this good? Does it mean anyone who could get on our network can see our USB disks attached to our AE base station? In the AE setup it says most of the time to connect the router to the AE via the WAN port of the AE. It does also say on page 23: "... Connect your DSL or cable modem to the AE Ethernet WAN port. If you are using an existing Ethernet network with Internet access to connect to the Internet, you can connect the AE to the Ethernet network instead." I assume that the former applies to us, but should we be using NAT and DHCP for security or is Bridge Mode OK? Having just had a single phone <> modem/router <> Mac setup for so long I get a bit confused over the extra connection setup of the Airport Extreme. Also, how do we provide a guest network with only Internet access but no access to our USB disks. This is a feature mentioned on Apple's AE web page but I can't find the instructions anywhere in the booklet. Sorry about all the length!
