    • It is useful for hosting websites, FTP servers, and other services behind a router.
    • You need a DDNS service provider, like www.dyndns.org or www.TZO.com.
    • Wildcards allow for multiple hostnames using the same domain name.

    Setting up a DDNS Service

    • Select your DDNS service provider (DynDNS or TZO)
    • Enter your email address, DDNS key, and domain name (if using TZO)
    • Router will display current internet IP Address (dynamic).
    • You can manually trigger an update by clicking the "Update" button.

    Advanced Routing

    • Operating Mode allows you to configure advanced functions - Dynamic and Static routing.
    • Dynamic Routing automatically adjusts packet traffic based on network layout and exchanges routing tables.
    • Static Routing creates a fixed pathway for network information to reach a specific destination.

    MAC Address Clone

    • MAC address is a unique code for hardware identification.
    • Some internet providers require you to register a MAC address.
    • If you don't want to re-register, you can clone the MAC address registered with your ISP to the router using the MAC Address Clone feature.

    NAT (Network Address Translation)

    • NAT is a feature that allows multiple devices on a local network to share a single public IP address.
    • Keep NAT enabled if the router is hosting your network's connection to the internet.
    • If another router exists on your network, disable NAT.
    • Disabling NAT will enable dynamic routing.

    Wireless Network Settings

    • You can configure wireless networks manually or use Wi-Fi Protected Setup.
    • Network Mode allows you to choose which wireless standards are enabled (Mixed, BG-Mixed, Wireless-N Only, Wireless-G Only, Wireless-B Only, or Disabled).
    • Network Name (SSID) is the name of your wireless network, visible to devices searching for a network.
    • Channel Width determines the bandwidth used by the network (20 MHz or 40 MHz). Auto setting is recommended.
    • Channel allows you to choose a specific channel for your wireless network.
    • SSID Broadcast determines whether the router broadcasts the SSID to make it visible to nearby devices.

    Wi-Fi Protected Setup - Wireless Network Configuration

    • Allows for easy wireless network setup.
    • Three methods are available: Button, PIN, or Router PIN.
    • Button Method:
      • Press the Wi-Fi Protected Setup button on the client device.

    • Six Wireless Security modes are supported: WPA Personal, WPA Enterprise, WPA2 Personal, WPA2 Enterprise, RADIUS, and WEP. -WPA Personal: Uses a pass phrase, key renewal and encryption methods (TKIP or AES).
    • WPA2 Enterprise: Requires a RADIUS server for authentication. -WPA2 Personal: Uses a pass phrase with encryption (AES or TKIP).
    • RADIUS: Uses a RADIUS server for authentication.
    • WEP: Basic encryption method (not as secure as WPA).
    • Wireless MAC Filter: Allows you to filter wireless users by MAC address.

    Port Range Forwarding

    • Forwards requests to specific servers based on IP address and port mapping rules
    • Used to assign static IP addresses for designated servers
    • Configure using the DHCP Reservation feature

    Port Range Triggering

    • Allows applications to open specific ports for communication
    • Requires entering the starting and ending port numbers for both the triggered and forwarded ranges
    • Uses information from the DHCP Client Table to identify the triggered port number range

    DMZ (Demilitarized Zone)

    • Exposes one network computer to the Internet for specific services (e.g., gaming, videoconferencing)
    • Forwards all ports to the designated computer
    • Less secure than Port Range Forwarding because it opens all ports
    • Requires disabling DHCP client function on the DMZ computer and assigning a static IP address

    Quality of Service (QoS)

    • Ensures better service for high-priority network traffic (e.g., videoconferencing)
    • Configurable with a variety of settings, including support for Wi-Fi Multimedia (WMM) and No Acknowledgement
    • Prioritizes network traffic into four levels: High, Medium, Normal, and Low
