Access Control List

You can Specify what kind of service should be enabled in WAN on this page. Packets available in the ACL list or from IP specified can enter the AP Router.

Port Triggering

Port Triggering is a special form of Port Forwarding in which it requires an outgoing connection before allowing incoming connections on a single or multiple port. Port Triggering is mostly used when your computer is behind a NAT router. For example, if a gaming application sends outgoing data on ports 5000-6000 but receives the incoming data on port 111, typically behind a NAT router the router simply drops the data because it does not know which computer it should send requests to. But with port triggering you can tell the router to allow incoming data on port 111 when an outgoing data sends it through ports 5000-6000. It gives more flexibility than static port forwarding because you don't need to set it up for a specific computer.

DMZ

DMZ means "Demilitarized Zone." If an application has trouble working from behind the router, you can expose one computer to the Internet and run the application on that computer. When a LAN host is configured as a DMZ host, it becomes the destination for all incoming packets that do not match some other incoming session or rule. If any other ingress rule is in place, that will be used instead of sending packets to the DMZ host; so, an active session, virtual server, active port trigger, or port forwarding rule will take priority over sending a packet to the DMZ host. (The DMZ policy resembles a default port forwarding rule that forwards every port that is not specifically sent anywhere else). Note:Putting a computer in the DMZ may expose that computer to a variety of security risks. Use of this option is only recommended as a last resort. Specify the LAN IP address of the LAN computer that you want to have unrestricted Internet communication. If this computer obtains its address Automatically using DHCP, then you may want to make a static reservation on the Basic Network Settings page so that the IP address of the DMZ computer does not change.

URL Filter

Used to configure the keyword filter. You can add or remove keywords to filter. This feature can prevent LAN users to access the website with specific keywords.

IP/Port Filter

You can prevent certain local IP accessing Internet with IP port filter and block accessing to certain Internet services. For example, select protocol as "IP", rule action as "Deny", direction as "Downstream" and fill the IP/IP mask, that means downstream IP packets matching the source IP address and the destination IP address can not enter the internal network. Default Action Status Outgoing permit and Incoming deny by default. Rule Configuration Choose "Permit" or "Deny" to specify the rules. Items available: protocol, direction, source IP/source mask, destination IP/destination mask, source port/destination port. Current Filter Table The table lists the IP port filtering rules. You can add or delete entries in the table if needed.

MAC Filter

Used to limit the specific LAN packets sent to the Internet through the gateway. This feature can protect or restrict local LAN.

Dynamic DNS

Dynamic DNS: The host without a fixed IP can change the relationship between DNS and IP using a dynamic DNS service if the IP changes. You can configure dynamic DNS for DynDNS.org, TZO or Oray. You can add/delete a dynamic DNS. The account provided by DDNS service providers.

Traffic Control

Traffic Control Traffic control is a pro-active measures to adjust the output rate of flow. The role is to limit the outflow of a network traffic of a connection with sudden, so that such packets to send out a uniform rate. You can add traffic shaping rules. Auto Traffic Shaping Auto adjust all the current flow to make sure each flow send out a uniform rate.

UPnP

UPnP is short for Universal Plug and Play, which is a networking architecture that provides compatibility among networking equipment, software, and peripherals. This router has optional UPnP capability, and can work with other UPnP devices and software.

Telnet

Telnet is a network protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection.
