  • Enabling or Disabling the Firewall
    The supports the firewall function to control the transmission of data streams and protect your local area network from unauthorized access.
  • Setting LAN IP Filtering

  • Configuring a Virtual Server
    The supports the virtual server to enable external users to use the services provided in the local area network (LAN) using the Hypertext Transfer Protocol (HTTP), File Transfer Protocol (FTP), and other protocols.
  • Configuring a Special Application
    The supports the function to use a special application to configure dynamic port forwarding. Certain applications in the local area network (LAN) must use a specified port of the firewall to access remote applications. To set up a Transmission Control Protocol and User Datagram Protocol (TCP/UDP) connection between an application in the LAN and a remote application, the firewall uses this port forwarding function to open the required port.
  • Setting the DMZ
    If external users cannot access certain network services provided by the local area network (LAN), use the DMZ function provided by the to set the client that provides the required network services as the DMZ host; external users can then access these services properly.

  • Setting the UPnP
    The Universal Plug and Play (UPnP) service realizes intelligent connection between two UPnP devices using port forwarding. UPnP devices can obtain IP addresses automatically and access the Internet dynamically.
  • Configuring NAT
    Network address translation is the process of modifying source and destination IP addresses when IP packets are transmitted across a router or firewall. The purpose of this process is to translate internal (private) IP addresses into external (public) IP addresses to provide a solution to the impending exhaustion of IP addresses. supports port-restricted cone NAT and symmetric NAT.
