• 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.
To remove DMZ: 1. Delete the client’s LAN IP address from the IP Address of Exposed Station text box. 2. When done, click Apply. 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.
NOTES: DDNS service will not work under these conditions: • When the xDSL modem 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. 4.3.7 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.
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 VPN Server field, select Yes. 3. On the Network Place (Samba) Support field, select Yes. 4.
4.6 Firewall The xDSL modem router can serve as a hardware firewall for your network. NOTE: The Firewall feature is enabled by default. 4.6.1 General To set up basic Firewall settings: 1. From the navigation panel, go to Advanced Settings > Firewall > General tab. 2. On the Enable Firewall field, select Yes. 3. On the Enable DoS protection, select Yes to protect your network from DoS (Denial of Service) attacks though this may affect your router’s performance. 4.
4.6.2 URL Filter You can specify keywords or web addresses to prevent access to specific URLs. NOTE: The URL Filter is based on a DNS query. If a network client has already accessed a website such as http://www.abcxxx.com, then the website will not be blocked (a DNS cache in the system stores previously visited websites). To resolve this issue, clear the DNS cache before setting up the URL Filter. To set up a URL filter: 1. From the navigation panel, go to Advanced Settings > Firewall > URL Filter tab. 2.
4.6.3 Keyword Filter Keyword filter blocks access to webpages containing specified keywords. To set up a keyword filter: 1. From the navigation panel, go to Advanced Settings > Firewall > Keyword Filter tab. 2. On the Enable Keyword Filter field, select Enabled. 3. Enter a word or phrase and click the button. 4. Click Apply. NOTES: 76 • The Keyword Filter is based on a DNS query. If a network client has already accessed a website such as http://www.abcxxx.
4.6.4 Network Services Filter The Network Services Filter blocks LAN to WAN packet exchanges and restricts network clients from accessing specific web services such as Telnet or FTP. To set up a Network Service filter: 1. From the navigation panel, go to Advanced Settings > Firewall > Network Service Filter tab. 2. On the Enable Network Services Filter field, select Yes. 3. Select the Filter table type. Black List blocks the specified network services.
