3. In the Domain Name text box, enter a domain name for the wireless router. 4. In the IP Pool Starting Address field, key in the starting IP address. 5. In the IP Pool Ending Address field, key in the ending IP address. 6. In the Lease Time field, specify in seconds when an assigned IP address will expire. Once it reaches this time limit, the DHCP server will then assign a new IP address. NOTES: • We recommend that you use an IP address format of 192.168.1.
4.2.3 Route If your network makes use of more than one wireless router, you can configure a routing table to share the same Internet service. NOTE: We recommend that you do not change the default route settings unless you have advanced knowledge of routing tables. To configure the LAN Routing table: 1. From the navigation panel, go to Advanced Settings > LAN > Route tab. 2. On the Enable static routes field, choose Yes. 3.
4.2.4 IPTV The wireless router supports connection to IPTV services through an ISP or a LAN. The IPTV tab provides the configuration settings needed to set up IPTV, VoIP, multicasting, and UDP for your service. Contact your ISP for specific information regarding your service.
4.3 WAN 4.3.1 Internet Connection The Internet Connection screen allows you to configure the settings of various WAN connection types. To configure the WAN connection settings: 1. From the navigation panel, go to Advanced Settings > WAN > Internet Connection tab. 2. Configure the following settings below. When done, click Apply. • WAN Connection Type: Choose your Internet Service Provider type. The choices are Automatic IP, PPPoE, PPTP, L2TP or fixed IP.
• 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.
• 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. To avoid connection issues due to an unregistered MAC address, you can: • Contact your ISP and update the MAC address associated with your ISP service.
4.3.2 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: 64 • 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.
4.3.3 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.
4.3.4 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.
4.3.5 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.
• Enable wildcard: Enable wildcard if your DDNS service requires one. NOTES: DDNS service will not work under these conditions: • When the wireless router is using a private WAN IP address (192.168. x.x, 10.x.x.x, or 172.16.x.x), as indicated by a yellow text. • The router may be on a network that uses multiple NAT tables. 4.3.6 NAT Passthrough NAT Passthrough allows a Virtual Private Network (VPN) connection to pass through the router to the network clients.
