Customizing Your Network

This chapter describes how to customize your network through the advanced settings on your

gateway. When you log in to the gateway, these tasks are grouped under Advanced.

This chapter includes:

•

“DMZ Host” on page 5-1

”

•

“LAN IP Setup” on page 5-2

•

“Configuring Universal Plug and Play (UPnP)” on page 5-5

•

Note:

For information about port forwarding, see

Log in to the gateway using its default address of

or at whatever IP address the

unit is currently configured. Use the default user name of

admin

and default password of

password

, or the password you have set up.

DMZ Host

You can use the DMZ Host screen to set up a default DMZ computer. Specifying a default

DMZ computer allows you to set up a PC that is available to anyone on the Internet for

services that you have not defined. There are security issues with doing this, so only set up

the DMZ host if you are willing to risk open access. If you do not define a DMZ host the

gateway discards any undefined service requests.
