Advanced > Firewall

Firewall Rules is an advance feature used to deny or allow traffic from passing

through the device. It works in the same way as IP Filters with additional settings. You

can create more detailed rules for the device.

Enabled or Disabled

Click

Enabled

to apply the filter policy or click

Disabled

to enter an inactive filter policy

(You can reactivate the policy later).

Name

Enter the name of the Firewall Rule.

Action

Select Allow or Deny to allow or deny traffic to pass through the DI-614+.

Interface Source

Choose between a LAN or WAN source. An asterisk signifies the selection of both

sources.

IP Start

The starting IP address for the filter policy. Leaving the field blank selects all IPs.

IP End

The ending IP address for the filter policy. Leaving the field blank sleects all IPs.

Interface Destination

Choose between a LAN or WAN destination. An asterisk signifies the selection of both

destinations.

and enter the time period during which the virtual service

will be available

Port Range

Enter in the port range of the TCP/UDP ports that you want the policy to apply to.

If it

is only a single port

that you want the policy applied to, then enter the port number in

the Start Port

field and leave the End Port field blank.

If you want to use all the ports,

you can leave the port range empty.

Protocol

Advanced

> DMZ

If you have a computer that cannot run Internet applications properly from behind the

DI-614+, then you can allow that computer to have unrestricted Internet access. Enter

the IP address of that computer as a DMZ (Demilitarized Zone) host with unrestricted

Internet access. Adding a client to the DMZ may expose that computer to a variety of

security risks, so only use this option as a last resort.

Beacon Interval

Beacons are packets sent by an Access Point to synchronize a

wireless network. Specify a value.

100

is the default setting and is

recommended.

TX Rates

Select the data rate. Default is

1-2-5.5-11-22Mbps

.

DTIM interval

(

D

elivery

T

raffic

I

ndication

M

3

is the default setting. A DTIM

is a countdown informing clients of the next window for listening to

broadcast and multicast messages.

Basic Rates

Preamble Type

Select the data rate. Default is

1-2-5.5-11-22Mbps

.

Long preamble

is the default setting. (High traffic networks should

use the shorter preamble type.) The preamble defines the length of

the CRC block used in communication between the Access Point

and the roaming wireless Network adapters.(Cyclic Redundancy

Check is a common technique for detecting data transmission

errors)

35

Using the Configuration Menu

Advanced > Performance (Continued)

SSID Broadcast

Enabled

is the default setting. Choose

Enabled

to broadcast

the SSID across the network. All devices on a network must

share the same SSID (Service Set Identifier) to establish

communication. Choose

Disabled

if you do not wish to

broadcast the SSID over the network.

Antenna transmit

power

4X Mode

The DI-614+ has the option to adjust its wireless transmit power.

Limiting transmit power can help in situations where you do not

want the same signals overlapping one another.

4x Mode

allows for higher speed wireless performance. Only

Antenna Selection

Diversity

External

Internal

In this mode, the DI-614+ only uses the internal antenna for

short distance coverage.

In this mode, the DI-614+ only uses the external antenna and

extends wireless coverage.

In this mode, the DI-614+ uses both the internal and external

antenna and then uses the antenna that picks up the strongest

signal.
