The ZoomAir Internet Gateway is the total package in home networking that I was looking for. In addition to the standard features such as a firewall, DMZ, Shared Internet Access, wireless and wired LAN, it can act as a print server with a built in parallel port. Another feature is the MAC Address control which allows the owner to limit the connections to known computers in your home or small business. The MAC Address control also limits to an extent the type of access each pc has on your network with router access control groups.
It is also very refreshing to actually have a well-written owner's manual included in the package that was easy to follow and made sense.
