Firewall Firewall 57 Some ISPs require a host name. If your ISP has this requirement, enter the host name in the Host Name field. 1 Three different ways to configure this page: ■ If your ISP requires an assigned MAC address, enter the values for a WAN MAC address or ■ If the computer you are now using is the one that was previously connected directly to the cable modem, select Clone or ■ To reset the MAC Address to the default, select Reset MAC. 2 Click Apply to save the settings. From these pages, you can configure settings for the firewall. Your Router is equipped with a firewall that will protect your network from a wide array of common hacker attacks including Ping of Death (PoD) and Denial of Service (DoS) attacks. You can turn the firewall function off if needed. Turning off the firewall protection will not leave your network completely vulnerable to hacker attacks, but 3Com recommends that you leave the firewall enabled whenever possible.
