1
Maximum wireless signal rate derived from IEEE Standard 802.11g, 802.11a, and Draft 802.11n specications. Actual data throughput will vary. Network conditions and
environmental factors, including volume of network trafc, building materials and construction, and network overhead, lower actual data throughput rate. Environmental
factors will adversely affect wireless signal range.
2
Frequency Range varies depending on country’s regulation.

- This section will allow you to change the local network settings of the router and to configure the dhcp settings 34
- Dhcp server settings 35
- Dhcp stands for dynamic host control protocol the dir 855 has a built in dhcp server the dhcp server will automatically assign an ip address to the computers on the lan private network be sure to set your computers to be dhcp clients by setting their tcp ip settings to obtain an ip address automatically when you turn your computers on they will automatically load the proper tcp ip settings provided by the dir 855 the dhcp server will automatically allocate an unused ip address from the ip address pool to the requesting computer you must specify the starting and ending address of the ip address pool 35
- Dhcp reservation 36
- If you want a computer or device to always have the same ip address assigned you can create a dhcp reservation the router will assign the ip address only to that computer or device 36
- Note this ip address must be within the dhcp ip address range 36
- Note if using the network usb option users will need to install the network usb utility into the computers to share the usb device through the router 37
- Note please see the shareport manual on the cd for more information 37
- Usb settings 37
- Use this section to configure your usb port there are two configurations to choose from network usb and wcn configuration 37
- Virtual server 38
- This will allow you to open a single port if you would like to open a range of ports refer to page 36 39
- Port forwarding 40
- This will allow you to open a single port or a range of ports 40
- Application rules 41
- Some applications require multiple connections such as internet gaming video conferencing internet telephony and others these applications have difficulties working through nat network address translation special applications makes some of these applications work with the dir 855 if you need to run applications that require multiple connections specify the port normally associated with an application in the trigger port field select the protocol type as tcp or udp then enter the firewall public ports associated with the trigger port to open them for inbound traffic 41
- The dir 855 provides some predefined applications in the table on the bottom of the web page select the application you want to use and enable it 41
- Qos engine 42
- The qos engine option helps improve your network gaming performance by prioritizing applications by default the qos engine settings are disabled and application priority is not classified automatically 42
- Network filters 43
- Use mac media access control filters to allow or deny lan local area network computers by their mac addresses from accessing the network you can either manually add a mac address or select the mac address from the list of clients that are currently connected to the broadband router 43
- Access control 44
- Access control wizard 44
- The access control section allows you to control access in and out of your network use this feature as parental controls to only grant access to approved sites limit web access based on time or dates and or block access from applications like p2p utilities or games 44
- Access control wizard continued 45
- Access control wizard continued 46
- Website filters 47
- Website filters are used to allow you to set up a list of allowed web sites that can be used by multiple users through the network to use this feature select to allow or deny enter the domain or website and click save settings you must also select apply web filter under the access control section page 40 47
- Inbound filters 48
- The inbound filter option is an advanced method of controlling data received from the internet with this feature you can configure inbound data filtering rules that control data based on an ip address range inbound filters can be used with virtual server port forwarding or remote administration features 48
- A firewall protects your network from the outside world the dir 855 offers a firewall type functionality the spi feature helps prevent cyber attacks sometimes you may want a computer exposed to the outside world for certain types of applications if you choose to expose a computer you can enable dmz dmz is short for demilitarized zone this option will expose the chosen computer completely to the outside world 49
- Firewall settings 49
- Application level gateway alg configuration 50
- 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 50
