host name in the Host Name field.

■ If your ISP requires an assigned MAC address, enter the values for a
WAN MAC address

Firewall 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.
