6.4.4 NAT

It’s separated into three parts: Virtual Servers, Port Trigger, and DMZ.

6.4.4.1 Virtual Servers

Virtual Server allows you to direct incoming traffic from WAN side (identified by Protocol,

IP address and service port) to the internal server with private IP address on the LAN

side. The Internal port is required only if the external port needs to be converted to a

different port number used by the server on the LAN side. (Figure 6-12-1, Figure 6-12-2)

Figure 6-12-1. Advanced Setup – NAT – Virtual Servers

Administrative Guide Configuration

Figure 6-12-2. Advanced Setup – NAT – Virtual Servers – Add

6.4.4.2 Port Triggering

Some applications require that specific port(s) in the Router's firewall be opened for

access by the remote parties. Port Trigger dynamically opens up the 'Open Ports' in the

firewall when an application on the LAN initiates a TCP/UDP connection to a remote

party using the 'Triggering Ports'. The Router allows the remote party from the WAN

side to establish new connections back to the application on the LAN side using the

'Open Ports'. (Figure 6-13-1, 6-13-2)

Figure 6-14. Advanced Setup – NAT – DMZ

6.4.5 Security

The configuration display only when WAN page’s security option is selected. It’s

separated into three parts: Incoming Filter, Output Filter, and Parental Control.

6.4.5.1 Incoming Filter

It allows the users to create a filter rule to identify incoming IP traffic by specifying a new

filter name and at least one condition. All of the specified conditions in this filter rule

must be satisfied for the rule to take effect. (Figure 6-15-1, Figure 6-15-2)

By default, all incoming IP traffic from the WAN will be blocked if it is not consistent with

the incoming filter rules. In fact, EUT has opened some necessary ports such as

web port, sip ports and rtp ports, to make sure that voice application can communicate

well.

Click on Add to create a class to identify the IP traffic by specifying at least one condition

below. If multiple conditions are specified, all of them should be satisfied to make sure

the rule will take effect. (Figure 6-18-1, Figure 6-18-2)

IP QoS is applied to the traffic from LAN to WAN; the traffic from WAN to LAN will not be

applied.

Enter the QoS class name for this policy. Define the priority for this policy, and the

priority will be used by the next bandwidth control setting. EUT will modify the IP

header with new IP Precedence and/or IP Type Of Service fields.

It’s a IP Layer QoS policy. At least (but not limited to) one condition must be configured.

6.5 Wireless

This directory display only when wireless card is installed in your EUT board. Use

the Wireless screen to configure the EUT for wireless access. It is separated into 6

parts:

z Basic

z Security

z MAC Filter

z Wireless Bridge

z Advanced

z Station Info

The configurable items for each part would be described in the following.

6.5.1 Basic

The page (Figure 6-21) allows you to configure basic feature of the wireless LAN

interface. You can enable or disable the wireless LAN interface, hide the network from

active scans, set the wireless network name (also known as SSID) and restrict the

channel set based on country requirement.

Figure 6-21. Wireless – Basic

6.5.2 Security

The page allows you to configure security features of the wireless LAN interface. You

can set the network authorization method, select data encryption, specify whether a

network key is required to authenticate to this wireless network and specify the

encryption strength.

The following items will be configured in the page:

Network Authentication: Set the network Authentication method. 802.1X and WPA

require setting valid RADIUS parameters. WPA-PSK requires a valid WPA Pre-Shared

Key to be set. (Figure 6-22-1)

Administrative Guide Configuration

802.1X: As the IEEE standard for access control for wireless and wired LANs, 802.1x

provides a means of authentication and authorizing devices to attach to a LAN port.

This standard defines the Extensible Authentication Protocol (EAP), which uses a

central authentication server to authenticate each user on the network.

WPA/WPA2: The Wi-Fi Alliance put together WPA/WPA2 as a data encryption method

for 802.11 wireless LANs. WPA is an industry-supported, pre-standard version of

802.11i utilizing the Tempoal Key Integrity Protocol (TKIP), which fixes the problems

of WEP, including using dynamic keys.

WPA/WPA2 Pre-Shared Key: Set the WPA/WPA2 Pre-Shared Key (PSK).

WPA/WPA2 Group Rekey Interval: Set the WPA/WPA2 Group Rekey Interval in

seconds. Leave blank or set to zero to disable periodic re-keying.

Figure 6-22-1. Wireless – Security

Radius Server: Set the IP address of the RADIUS server to use for authentication and

dynamic key derivation.

RADIUS Server is responsible for receiving user connection requests, authenticating

the user, and then returning all of the configuration information necessary for the client

to deliver the server to the user.

Radius Port: Sets the UDP port number of the RADIUS server. The port number is

usually 1812 or 1645 and depends on the server.

Radius Key: Set the shared secret for the RADIUS connection.

WEP Encryption: Selecting Disabled disables WEP data encryption. Selecting

Enabled enables WEP data encryption and requires that a valid network key be set

and selected unless 802.1X is enabled.

Administrative Guide Configuration

WEP, short for Wired Equivalent Privacy, is a protocol for wireless LANs or local area

networks. This WEP is defined in the 802.11 Standard. WEP is designed so security

levels are maintained at the same level as the wired LAN. WEP’s aim is to provide

security by encrypting data over radio waves. WEP protects data as it’s transmitted

from one end point to another. WEP is used at two lowest layers, the data link and

physical layer. WEP is designed to make up for the inherent security in wireless

transmission as compared to wired transmission.

Shared Key Authentication: Set whether shared key authentication is required to

associate. A valid network key must be set and selected if required. (Figure 6-22-2)

Figure 6-22-2. Wireless – Security – Encryption Keys

6.5.3 MAC Filter

Figure 6-23-1. Wireless – MAC Filter

Administrative Guide Configuration

This page allows users to Add/Remove hosts with the specified MAC addresses that

are able or unable to access the wireless network. When users decide to use Allow,

only the MAC addressed in the user-defined list can access the wireless network.

When users use Deny, only the user specified MAC addresses are unable to access

to wireless network. And if the Disable option is selected, all users will be able to

access to wireless network.

Note: The MAC addresses in the list would immediately take effect when Allow or

Deny is checked.

Figure 6-23-2. Wireless – MAC Filter – Allow/Deny

6.5.4 Wireless Bridge

It allows the users to configure wireless bridge features of the wireless LAN interface.

You can select Wireless Bridge (also known as Wireless Distribution System) to

disables access point functionality. Selecting Access Point enables access point

functionality. Wireless bridge functionality will still be available and wireless stations

will be able to associate to the AP. Select Disabled in Bridge restricts which disables

wireless bridge restriction. Any wireless bridge will be granted access. Selecting

Enabled or Enabled (Scan) enables wireless bridge restriction. Only those bridges

selected in Remote Bridges will be granted access.(Figure 6-24).

Administrative Guide Configuration

Figure 6-24. Wireless – Wireless Bridge

6.5.5 Advanced

It allows you to configure advanced features of the wireless LAN interface. You can

select a particular channel on which to operate, force the transmission rate to a

particular speed, set the fragmentation threshold, set the RTS threshold, set the wakeup

interval for clients in power-save mode, set the beacon interval for the access point, set

XPress mode and set whether short or long preambles are used

Channel: Select the appropriate channel from the list provided to correspond with your

network settings. All devices in your wireless network must use the same channel in

order to function correctly.

Rate: The default setting is Auto. The range is from 1 to 54Mbps. The rate of data

transmission should be set depending on the speed of your wireless network. You can

select from one transmission speed, or keep the default setting, Auto, to have the IAD

automatically use the fastest possible data rate.

Multicast Rate: The default setting is 54Mbps. The range is from 1 to 54Mbps. The

rate of data transmission should be set depending on the speed of your wireless

network. You can select from one transmission speed, or keep the default setting, to

have the IAD automatically use the fastest data rate for multicast packets.

Basic Rate: Select the basic rate that wireless clients must support.

Fragmentation Threshold: This value should remain at its default setting of 2346. The

range is 256~2346 bytes. It specifies the maximum size for a packet before data is

fragmented into multiple packets. If you experience a high packet error rate, you may

slightly increase the Fragmentation Threshold. Setting this value too low may result in

poor network performance. Only minor modifications of this value are recommended.

Administrative Guide Configuration

Figure 6-25. Wireless – Advanced

RTS Threshold: This value should remain at its default setting of 2347. The range is

0~2347 bytes. Should you encounter inconsistent data flow, only minor modifications

are recommended. If a network packet is smaller than the packet RTS threshold size,

the RTS/CTS mechanism will not be enabled. The IAD sends Request of Send (RTS)

frames to a particular receiving station and negotiates the sending of a data frame.

After receiving an RTS, the wireless station responds with a Clear to Send (CTS)

frame to acknowledge the right to begin transmission.

DTIM Interval: The default value is 3. This value, between 1 and 255 milliseconds,

indicates the interval of the Delivery Traffic Indication Message (DTIM). A DTIM field is

a countdown field informing clients of the next window for listening to broadcast and

multicast messages. When the router has buffered broadcast or multicast for

associated clients, it sends the next DTIM with a DTIM Interval value. Its clients hear

the beacons and awaken to receive the broadcast and multicast message.

Beacon Interval: The default value is 100. Enter a value between 1 and 65535

milliseconds. The Beacon Interval value indicates the frequency interval of the beacon.

A beacon is a packet broadcast by the router to synchronize the wireless network.

XPress™ Technology: Select to enable/disable this proprietary mode.

54g™ Mode: Select the mode to 54g Auto for the widest compatibility. Select the

mode to 54g Performance for the fastest performance among 54g certified equipment.

Set the mode to 54g LRS if you are experiencing difficulty with legacy 802.11b

equipment.

Administrative Guide Configuration

54g protection: In Auto mode the IAD will use RTS/CTS to improve 802.11g

performance in mixed 802.11g/802.11b networks. Turn protection off to maximize

802.11g throughput under most conditions.

WMM (WiFi Multimedia): Select to enable/disable the support.(Figure 6-25)
