2 Getting started 2.1 Logging into the Web GUI Your ASUS Wireless xDSL Modem Router comes with an intuitive web graphical user interface (GUI) that allows you to easily configure its various features through a web browser such as Internet Explorer, Firefox, Safari, or Google Chrome. NOTE: The features may vary with different firmware versions. To log into the web GUI: 1. The web GUI launches automatically when you open a web browser. If it does not auto-launch, enter http://router.asus. com 2.
Top command buttons QIS Information banner Navigation panel right column middle column NOTE: If you are logging into the Web GUI for the first time, you will be directed to the Quick Internet Setup (QIS) page automatically.
2.2 Quick Internet Setup (QIS) Wizard with Auto-detection The Quick Internet Setup (QIS) function guides you in quickly setting up your Internet connection. NOTE: When setting the Internet connection for the first time, press the Reset button on your xDSL modem router to reset it to its factory default settings. For more details, refer to the section Firmware Restoration in Chapter 5 of this user manual. To use QIS with auto-detection: 1. Log into the Web GUI. The QIS page launches automatically.
2. Your xDSL modem router automatically configures the DSL Annex mode, Internet connection type, and VPI/VCI value and encapsulation modes. Key in the Internet account information from your Internet Service Provider (ISP). IMPORTANT! Obtain the necessary information from your ISP to configure the Internet connection. NOTES: 16 • The auto-detection of your ISP connection type takes place when you configure your xDSL modem router for the first time or when your device is reset to its default settings.
3. If QIS failed to detect your Internet connection type, follow the steps below to manually configure your connection settings: a) Select the Annex mode that your DSL service uses. NOTES: • Annex A or Annex B mode has multiple modes: Annex A/I/J/L/M or Annex B/J. If your ISP DSLAM offers both Annex A and Annex M mode, QIS automatically set the Annex mode to Annex A/I/J/L/M mode and completes the DSL line setting.
b) Select your Country and Internet Service Provider (ISP). c) Assign the wireless network name (SSID) and security key for your wireless connection. Click Apply when done. d) A summary page appears to show the current settings for your network. Click Next to save your network settings and go to the Network Map page.
2.3 Connecting to your wireless network After setting up your xDSL modem router via QIS, you can connect your computer or other smart devices to your wireless network. To connect to your network: 1.

• Special Requirement from ISP • Host Name: This field allows you to provide a host name for your router. It is usually a special requirement from your ISP. If your ISP assigned a host name to your computer, enter the host name here. • MAC Address: MAC (Media Access Control) address is a unique identifier for your networking device. Some ISPs monitor the MAC address of networking devices that connect to their service and reject any unrecognized device that attempt to connect.
4.3.3 Port Trigger Port range triggering opens a predetermined incoming port for a limited period of time whenever a client on the local area network makes an outgoing connection to a specified port. Port triggering is used in the following scenarios: • More than one local client needs port forwarding for the same application at a different time. • An application requires specific incoming ports that are different from the outgoing ports. To set up Port Trigger: 1.
• Trigger Port: Specify a trigger port to open the incoming port. • Protocol: Select the protocol, TCP, or UDP. • Incoming Port: Specify an incoming port to receive inbound data from the Internet. • Protocol: Select the protocol, TCP, or UDP. NOTES: • When connecting to an IRC server, a client PC makes an outgoing connection using the trigger port range 66660-7000. The IRC server responds by verifying the username and creating a new connection to the client PC using an incoming port.
4.3.4 Virtual Server/Port Forwarding Port forwarding is a method to direct network traffic from the Internet to a specific port or a specific range of ports to a device or number of devices on your local network. Setting up Port Forwarding on your router allows PCs outside the network to access specific services provided by a PC in your network.
2. Configure the following settings below. When done, click Apply. • Enable Port Forwarding: Choose Yes to enable Port Forwarding. • Famous Server List: Determine which type of service you want to access. • Famous Game List: This item lists ports required for popular online games to work correctly. • FTP Server Port: Avoid assigning the port range 20:21 for your FTP server as this would conflict with the router’s native FTP server assignment. • Service Name: Enter a service name.
• Local IP: Key in the client’s LAN IP address. NOTE: Use a static IP address for the local client to make port forwarding work properly. Refer to section 4.2 LAN for information. • Local Port: Enter a specific port to receive forwarded packets. Leave this field blank if you want the incoming packets to be redirected to the specified port range. • Protocol: Select the protocol. If you are unsure, select BOTH.
4.3.5 DMZ Virtual DMZ exposes one client to the Internet, allowing this client to receive all inbound packets directed to your Local Area Network. Inbound traffic from the Internet is usually discarded and routed to a specific client only if port forwarding or a port trigger has been configured on the network. In a DMZ configuration, one network client receives all inbound packets. Setting up DMZ on a network is useful when you need incoming ports open or you want to host a domain, web, or e-mail server.
4.3.6 DDNS Setting up DDNS (Dynamic DNS) allows you to access the router from outside your network through the provided ASUS DDNS Service or another DDNS service. To set up DDNS: 1. From the navigation panel, go to Advanced Settings > WAN > DDNS tab. 2. Configure the following settings below. When done, click Apply. • Enable the DDNS Client: Enable DDNS to access the ASUS router via the DNS name rather than WAN IP address. • Server and Host Name: Choose ASUS DDNS or other DDNS.
4.3.7 NAT Passthrough NAT Passthrough allows a Virtual Private Network (VPN) connection to pass through the router to the network clients. PPTP Passthrough, L2TP Passthrough, IPsec Passthrough, RTSP Passthrough, H.323 Passthrough, and SIP Passthrough are enabled by default. To enable / disable the NAT Passthrough settings, go to the Advanced Settings > WAN > NAT Passthrough tab. When done, click Apply.
4.4 IPV6 This xDSL modem router supports IPv6 addressing, a system that supports more IP addresses. This standard is not yet widely available. Contact your ISP if your Internet service supports IPv6. To set up IPv6: 1. From the navigation panel, go to Advanced Settings > IPv6. 2. Select your Connection Type. The configuration options vary depending on your selected connection type. 3. Enter your IPv6 LAN and DNS settings. 4. Click Apply.
4.5 VPN Server VPN (Virtual Private Network) provides a secure communication to a remote computer or remote network using a public network such as the Internet. NOTE: Before setting up a VPN connection, you would need the IP address or domain name of the VPN server you are trying to access. To set up access to a VPN server: 1. From the navigation panel, go to Advanced Settings > VPN Server. 2. On the Enable PPTP VPN Server field, select ON. 3.
