Even if you don't store important data on your network, an outside intruder can still bring it down. These devices are not routers in the truest sense, and you'll need to provide your own connection to the Internet, but they do sit between your connection and your LAN to protect your PCs and data. Cost Smaller organizations often don't want to spend a lot of money for security, and fortunately these products are inexpensive. Features All of these products offer at least a WAN port for connection to your Internet router and a LAN port for connecting to the network. Gateway Router and WebRamp lack hub ports, which means that with these you'll have to invest in another box.
Any successful product designed for small-office use needs to be easy to install.
All of the products we looked at here are fairly easy to set up. Fortunately, the RT311 and DI-701 include a Windows GUI for configuring the unit. We recommend that you use the devices in their default configurations. Although you can turn specific ports on and off and set up complex filters to block specific IP addresses, all of these devices are preconfigured with NAT and, with the exception of the DI-701, are set up to prevent most DoS attacks, including SYN floods, Ping of Death, and IP spoofing. The SonicWall also relies mostly on NAT for protection, but it does include several features to combat DoS attacks and offers both port and address filtering.
