Input Protocol Select the protocol used by the Internet traffic coming back into the router through the opened port range (for example Both).
  • Page 32 Advanced_Gaming Multiple connections are required by some applications, such as internet games, video conferencing, Internet telephony, and others. These applications have difficulties working through NAT (Network Address Translation). This section is used to open multiple ports or a range of ports in your router and redirect data through those ports to a single PC on your network.
  • Page 33 Give the rule a name that is meaningful to you, for example Game Server. You can also select from a list of popular games, and many of the remaining configuration values will be filled in accordingly. However, you should check whether the port values have changed since this list was created, and you must fill in the IP address field.
  • Page 34 Advanced_StreamEngine The StreamEngine feature helps improve your network gaming performance by prioritizing the data flows of network applications. StreamEngine Setup Enable StreamEngine Enable this option for better performance and experience with online games and other interactive applications, such as VoIP.
  • Page 35 Automatic Classification This option is enabled by default so that your router will automatically determine which programs should have network priority. Dynamic Fragmentation This option should be enabled when you have a slow Internet uplink. It helps to reduce the impact that large low priority network packets can have on more urgent ones by breaking the large packets into several smaller packets.
  • Page 36 that every flow defined in a rule receives the expected priority and avoids indeterminate prioritization that could reduce QoS effectiveness. Name Create a name for the rule that is meaningful to you. Priority The priority of the message flow is entered here -- 1 receives the highest priority (most urgent) and 255 receives the lowest priority (least urgent).
  • Page 37 Advanced_Routing Add/Edit Route Adds a new route to the IP routing table or edits an existing route. Enable: Specifies whether the entry will be enabled or disabled. Destination IP: The IP address of packets that will take this route. Netmask: One bits in the mask specify which bits of the IP address must match.

MAC Address Enter the MAC address of the desired computer or connect to the router from the desired computer and click the Copy Your PC’s MAC Address button.
  • Page 45 Advanced_Firewall The router provides a tight firewall by virtue of the way NAT works. Unless you configure the router to the contrary, the NAT does not respond to unsolicited incoming requests on any port, thereby making your LAN invisible to Internet cyber attackers. However, some network applications cannot run with a tight firewall.
  • Page 46 Firewall Settings Enable SPI SPI ("stateful packet inspection" also known as "dynamic packet filtering") helps to prevent cyber attacks by tracking more state per session. It validates that the traffic passing through that session conforms to the protocol. When the protocol is TCP, SPI checks that packet sequence numbers are within the valid range for the session, discarding those packets that do not have valid sequence numbers.
  • Page 47 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.
  • Page 48 Non-UDP/TCP/ICMP LAN Sessions When a LAN application that uses a protocol other than UDP, TCP, or ICMP initiates a session to the Internet, the router's NAT can track such a session, even though it does not recognize the protocol. This feature is useful because it enables certain applications (most importantly a single VPN connection to a remote host) without the need for an ALG.
  • Page 49 Allows FTP clients and servers to transfer data across NAT. Refer to the Advanced → Virtual Server H.323 (Netmeeting) Allows H.323 (specifically Microsoft Netmeeting) clients to communicate across NAT. Note that if you want your buddies to call you, you should also set up a virtual server for NetMeeting.

  • Page 50: Advanced_Inbound Filter

    Advanced_Inbound Filter When you use the Virtual Server, Gaming, or Remote Administration features to open specific ports to traffic from the Internet, you could be increasing the exposure of your LAN to cyber attacks from the Internet. In these cases, you can use Inbound Filters to limit that exposure by specifying the IP addresses of internet hosts that you trust to access your LAN through the ports that you have opened.
  • Page 51 Add/Edit Inbound Filter Rule Here you can add entries to the Inbound Filter Rules List below, or edit existing entries. Name Enter a name for the rule that is meaningful to you. Action The rule can either Allow or Deny messages. Source IP Range Define the ranges of Internet addresses this rule applies to.
