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

“NAT” on page 5-6

Note: For information about port forwarding, see “Firewall Rules” on page 3-5.

Log in to the gateway using its default address of http://192.168.0.1 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.
