•  Enable:  Select Yes to enable the Internet access. Select No 

to disable the Internet access.

•  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.

•  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.
