Advanced Router Configuration
For most users, the default settings of the router are exactly what they need; there is no reason for them go beyond the basic configuration we’ve already discussed. However, if one of the following conditions applies to your PC and network, you will need to delve into the more advanced configuration options of the router:
∙Your ISP gives you a static IP address.
∙Your ISP requires PPPoE support.
∙Your ISP requires you to have a specific MAC or hardware address to connect to the network (MAC address spoofing).
∙You want to make sure a particular PC (e.g., a mail server or a web host) always gets the same IP address.
∙You need to run an Internet server or a web host from within the firewall (port mapping function).
∙You want to use the Universal Plug and Play feature (UPnP).
∙You have programs that must operate outside the firewall (DMZ function).
∙You want to block an external PC from communicating with your network (MAC address blocking).
∙You need to configure the router’s DHCP settings or configure the router to operate within a LAN that has an existing DHCP server.
∙You want to route or block data based on information in each individual data packet (packet filtering feature).
