The menu system is quite straightforward. Top-level menus are listed on a horizontal bar across the top of the screen. As you choose a menu item, a sub menu with additional options appears on a vertical bar along the left side of the screen. Most of the menus are self-explanatory, so I’ll just touch on the highlights for each top-level menu.
Networking – This menu lets you configure settings for both your WAN and your LAN. The built-in DHCP server, enabled by default, supports DHCP reservation and lets you clone currently-attached MAC addresses. The Square One also supports 12 DDNS (Dynamic DNS) providers (Figure 5) so you can host your web site even if your ISP provides you with a dynamic address. I tested DDNS using TZO.com as my provider and even behind two routers, the host name properly resolved to my public IP address.

Wireless – There is software support for wireless networking so that you can use the Square One as a wireless access point, but my test unit didn’t have the supporting hardware installed. Quad Micro Works will be shipping a wireless version, but it wasn’t available when my review unit was shipped. I did note, however, that the wireless software is quite basic. This version of the software doesn’t support WPA (Wi-Fi Protected Access), nor can you disable SSID broadcast or turn off the radio.
Server – This menu lets you add users and groups, set permissions, start/stop services (Figure 6) and access hard disk tools. As you create a user, a "home" directory is automatically created. You can set disk quotas for each user, as well as permissions. Default permissions are in the standard Linux format and are 770. A click of the help button opens a separate browser window with context sensitive help. I did note that under disk usage by user, the Square One improperly reported usage for my account (I copied 42GB of music to my home directory) as administrator disk usage.

Security – This menu (Figure 7) lets you set up your firewall, as well as create rules that control local access to the Internet. You can map ports to forward traffic from the WAN to specific IP addresses, or set up port triggering for gaming applications. However, unlike some of the routers on the market, none of the lists is pre-populated with services or applications, so you’ll need to know port information before you can configure rules.

Applications - The Square One ships with a suite of Internet applications pre-installed (Figure 8). Installed applications include Website Baker, a simple tool to create web sites, WordPress, a popular blogging program, PunBB and Web Drive. Unfortunately, none of these applications came with any documentation; to use them, you’ll have to find documentation on the Internet.
