If this computer obtains it’s IP address automatically using DHCP, be sure to make a static reservation on the Basic > DHCP page so that the IP address of the DMZ machine does not change. Application Level Gateway Configuration Here you can enable or disable ALG’s. Some protocols and applications require special handling of the IP payload to make them work with network address translation (NAT). Each ALG provides special handling for a specific protocol or application. A number of ALGs for common applications are enabled by default. Allows multiple machines on the LAN to connect to their corporate network using PPTP protocol. Allows multiple VPN clients to connect to their corporate network using IPSec. Some VPN clients support traversal of IPSec through NAT. This ALG may interfere with the operation of such VPN clients. If you are having trouble connecting with your corporate network, try turning this ALG off. Please check with the system administrator of your corporate network whether your VPN client supports NAT traversal. Allows applications that use Real Time Streaming Protocol to receive streaming media from the internet. QuickTime and Real Player are some of the common applications using this protocol. Allows devices and applications using VoIP (Voice over IP) to communicate across NAT. Some VoIP applications and devices have the ability to discover NAT devices and work around them. This ALG may interfere with the operation of such devices. If you are having trouble making VoIP calls, try turning this ALG off. PPTP: IPSEC (VPN): RTSP: SIP: Routing The Routing option is an advanced method of customizing specific routes of data through your network. Enter the IP address of packets that will take this route. Enter the netmask of the route, please note that the octets must match your destination IP address. Enter your next hop gateway to be taken if this route is used. The route metric is a value from 1 to 16 that indicates the cost of using this route. A value 1 is the lowest cost and 15 is the highest cost. Select the interface that the IP packet must use to transit out of the router when this route is used. Destination IP: Netmask: Gateway: Metric: Interface: Advanced Wireless Settings Transmit Power: Beacon Period: RTS Threshold: Fragmentation Threshold: DTIM Interval: WMM Function: Short GI: Set the transmit power of the antennas. Beacons are packets sent by the wireless router to synchronize a wireless network. Specify a value. 100 is the default setting and is recommended. This value should remain at its default setting of 2432. If inconsistent data flow is a problem, only a minor modification should be made. The fragmentation threshold, which is specified in bytes, determines whether packets will be fragmented. Packets exceeding the 2346 byte setting will be fragmented before transmission. 2346 is the default setting. (Delivery Traffic Indication Message) 3 is the default setting. A DTIM is a countdown informing clients of the next window for listening to broadcast and multicast messages. WMM is QoS for your wireless network. This will improve the quality of video and voice applications for your wireless clients. Check this box to reduce the guard interval time therefore increasing the data capacity. However, it’s less reliable and may create higher data loss. WISH Settings WISH is short for Wireless Intelligent Stream Handling, a technology developed to enhance your experience of using a wireless network by prioritizing the traffic of different applications. Enable WISH: Enable this option if you want to allow WISH to prioritize your traffic. Allows the router to recognize HTTP transfers for many common audio and video streams and prioritize them above other traffic. Such streams are frequently used by digital media players. HTTP: Windows Media Center: Enables the router to recognize certain audio and video streams generated by a Windows Media Center PC and to prioritize these above other traffic. Such streams are used by systems known as Windows Media Extenders, such as the Xbox 360. Automatic: When enabled, this option causes the router to automatically attempt to prioritize traffic streams that it doesn’t otherwise recognize, based on the behavior that the streams exhibit. This acts to deprioritize streams that exhibit bulk transfer characteristics, such as file transfers, while leaving interactive traffic, such as gaming or VoIP, running at a normal priority. WISH Rules: A WISH Rule identifies a specific message flow and assigns a priority to that flow. For most applications, the priority classifiers ensure the right priorities and specific WISH Rules are not required. WISH supports overlaps between rules. If more than one rule matches for a specific message flow, the rule with the highest priority will be used.
