Hi Phil LAN (local area network) : Anything on your network at home WAN (wide area network) : Anything beyond your router NAT (network address translation) : The translation between your private network and the rest of the world (public network). This job's done by your router. The router's firewall is what allows data through from the internet to your computer DHCP : Automatically giving configuring something with an IP address, everything on your home network must have a unique IP address or the router won't know where to send the data
If your router & your Airport are both set to create private networks (using NAT & DHCP) then anything connected to your Airport router will be invisible to the rest of the network as they are in their own private network. If you set the Airport to bridge mode, it just bridges the wireless & the wired networks without any private network creation, everything exists on the same network. Hope that helps!
