Introduction
Congratulations on your purchase of the NetComm Cable/DSL Firewall Router. The NetComm
Cable/DSL Firewall Router is designed to provide advanced networking security and network
resource sharing, utilising fast Ethernet connections with four built-in 10/100 auto-sensing
switched Ethernet ports. And best of all, with a powerful firewall engine, this device is able to
prevent DoS attack and uses SPI to provide superior protection for your private network from
Internet hackers.
The built-in NAT provides a natural Internet firewall, protecting your network from
unauthorised access by outside users. The router will share your internet connection with up to
253 users, 25 of which can be connected via NetComm Wireless Client Adaptors (NP7030 and
NP7040). Configured as a DHCP server, the NetComm Cable/DSL Firewall Router assigns an
IP Address to every computer connected on the LAN automatically. Also, a DHCP client helps
the WAN port to acquire an IP address dynamically from your ISP.
Unlike other typical routers, which only share 10Mbps over all of their connections, the
NetComm Cable/DSL Firewall Router is equipped with a 4-port 10M/100Mbps auto-sensing
switch, dedicating a possible100Mbps to each and every ethernet connected computer.
With a web-based UI (User Interface), this NetComm Cable/DSL Firewall Router is easy to
setup and maintain via web browsers such as Netscape Communicator and Internet Explorer.
