• Enable: Select Yes to enable the Internet access. Select No
to disable the Internet access.
• Basic Config
• IP version: Select your IP version type. The choices are IPv4,
IPv4/IPv6, and IPv6.
• WAN Connection Type: Select the correct connection type
based on your ISP service type. The choices are Automatic
IP, Static IP, and PPPoE.
• Enable UPnP: UPnP (Universal Plug and Play) allows several
devices (such as routers, televisions, stereo systems, game
consoles, and cellular phone) to be controlled via an IP-based
network with or without a central control through a gateway.
UPnP connects PCs of all form factors, providing a seamless
network for remote configuration and data transfer. Using
UPnP, a new network device is discovered automatically.
Once connected to the network, devices can be remotely
configured to support P2P applications, interactive gaming,
video conferencing, and web or proxy servers. Unlike Port
forwarding, which involves manually configuring port
settings, UPnP automatically configures the router to accept
incoming connections and direct requests to a specific PC on
the local network.
• IPv4 Setting
• Connect to DNS Server automatically: Allows this router
to get the DNS IP address from the ISP automatically. A DNS
is a host on the Internet that translates Internet names to
numeric IP addresses.
• Enable NAT: NAT (Network Address Translation) is a system
where one public IP (WAN IP) is used to provide Internet
access to network clients with a private IP address in a LAN.
The private IP address of each network client is saved in a
NAT table and is used to route incoming data packets.
