DIR-120 Ethernet Broadband Router Basic Router Configuration The first time you setup the Router it is recommended that you configure the WAN connection using a single computer making sure that both the computer and the Router are not connected to the LAN. Once the WAN connection is functioning properly, you may continue to make changes to Router configuration including IP settings and DHCP setup. This chapter is concerned mainly with using your computer to configure the WAN connection.
DIR-120 Ethernet Broadband Router Accessing the Configuration Manager Now that your computer’s IP settings allow it to communicate with the Router, you can access the configuration software. To use the web-based management software, launch a suitable web browser and direct it to the IP address of the Router. Type in http:// followed by the default IP address, 192.168.0.1 in the address bar of the browser. The URL in the address bar should read: http://192.168.0.1.
DIR-120 Ethernet Broadband Router Login Use the default user name “admin” and no password for first time setup. You should change the web-based manager access user name and password once you have verified that a connection can be established. The user name and password allows any PC within the same subnet as the Router to access the web-based manger.
DIR-120 Ethernet Broadband Router Web Manager The Web Manager used for configuration uses directories to organize the various menus used to configure and monitor the Router.

Your ISP should provide this IP address along with other account information. Click Next to continue.
DIR-120 Ethernet Broadband Router Setup Wizard – Configure Dynamic IP Address Connection For Dynamic IP Address connections, you may want to copy the MAC address of your Ethernet adapter to the Router. Some ISPs use the unique MAC address of your computer’s Ethernet adapter for identification and for IP address assignment (DHCP) when you first access their network. This can prevent the Router (which has a different MAC address) from being allowed access to the ISP’s network (and the Internet).
DIR-120 Ethernet Broadband Router Setup Wizard – Configure Static IP Address Connection For Static IP Address connection types, you must type in the IP Address, Subnet Mask, Gateway Address, Primary DNS Address and Secondary DNS Address (optional). Your ISP should provide this information to you. Click Next to continue. Static IP Connection Settings IP Address The public or global IP address provided by your ISP. Subnet Mask The Subnet Mask used for the Internet.
DIR-120 Ethernet Broadband Router Setup Wizard – Configure PPTP Client Connection The Router supports Point-to-Point Tunneling Protocol (PPTP) for the Internet connection. PPTP is also used for Virtual Private Networks (VPN). Some ISPs use PPTP to establish a client-to-server connection to their network, and ultimately to the Internet.
DIR-120 Ethernet Broadband Router Setup Wizard – Configure PPTP Client Connection The Router supports Point-to-Point Tunneling Protocol (L2TP) for the Internet connection. L2TP is also used for Virtual Private Networks (VPN). Some ISPs use L2TP to establish a client-to-server connection to their network, and ultimately to the Internet.

The menu configuration parameters in the display will change according to the connection option you choose.
DIR-120 Ethernet Broadband Router Dynamic IP (DHCP) Internet Connection A Dynamic IP Address connection configures the Router to automatically obtain its global IP address from a DHCP server on the ISP’s network. The service provider assigns a global IP address from a pool of addresses available to the service provider. Typically the IP address assigned has a long lease time, so it will likely be the same address each time the Router requests an IP address.
DIR-120 Ethernet Broadband Router Static IP Internet Connection Your ISP should provide IP settings information needed for your public IP address and other settings using the Static IP connection type. After configuration of Internet and local network IP settings is complete, click the Save Settings button to save the configuration changes made and reboot the Router. Static IP Internet Connection configuration menu IP Address Type in the public or global IP address provided by your ISP.
DIR-120 Ethernet Broadband Router PPPoE PPP or Point-to-Point protocol is a standard method of establishing a network connection/session between networked devices. Different forms of PPP include PPPoA and PPPoE (discussed below) involve an authentication process that requires a username and password to gain access to the network. PPPoE (PPP over Ethernet), as described in RFC 2516, is a method of using PPP through the Ethernet network. To configure the connection for PPPoE, perform the steps listed below.
DIR-120 Ethernet Broadband Router The table below describes the PPPoE Internet Connection menu settings. User Name The user name supplied to you by your ISP. Password The password supplied to you by your ISP. Retype Password Retype the password entered in the Password feld. Service Name Enter the service name supplied to you by your ISP, if required.
