The private local network, connected to the LAN port or wireless interface,
provides a Dynamic Host Configuration Protocol (DHCP) server for
allocating IP addresses to local PCs and wireless clients, and Network
Address Translation (NAT) for mapping the multiple ―internal‖ IP addresses
to one ―external‖ IP address.
The public external network, connected to the WAN port, supports DHCP
client, Point-to-Point Protocol over Ethernet (PPPoE) and static IP for
connection to an Internet service provider (ISP) through a cable or DSL
modem.
The Wireless Router can provide an access point service for an existing
wired LAN, creating a wireless extension to the local network. The Wireless
Router functions as purely an access point when set to Bridge Mode. When
used in this mode, there are no gateway functions between the WAN port
and the LAN and wireless interface.
A Wi-Fi wireless network is defined by its Service Set Identifier (SSID) or
network name. Wireless clients that want to connect to a network must set
their SSID to the same SSID of the network service.
