Excerpt: The product is primarily a Java and XML web browser-based application. The device also includes a stateful inspection (SPI) firewall and a network address translation feature. The unit ships with four LAN Ethernet interfaces and one WAN connection. However, each LAN connection is based on a single LAN IP and you cannot address every interface individually. The WAN interface provides options for DHCP and PPPoE, as well as a statically configured IP address.
