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.

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
Select one of the following protocols: TCP, UDP, or ICMP.

> 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)

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
other devices that support
4x Mode
will be able to take ad-
vantage of the higher performance.
Antenna Selection
Select Internal Antenna, External Antenna, or Diversity Antenna.
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.
