Section 3 - Configuration
Advanced
QoS Engine
Under
Connected Clients
, you will see client cards representing each device. If some
client cards are off-screen, you can use the
<
and
>
buttons to scroll left and right.
A maximum of
one
device can be assigned
Highest
priority.
A maximum of
two
devices can be assigned
High
priority.
A maximum of
eight
devices can be assigned
Medium
priority.
If connected clients are not assigned a priority, all devices will be treated with equal
priority. If some devices are assigned a priority and others are not, the unassigned
devices will be treated with the lowest priority.
Quality of Service (QoS) improves data flow. It allows you to prioritize clients, so that high-priority clients receive higher bandwidth. For example, if
one client is streaming a movie and another is downloading a non-urgent file, you might wish to assign the former client a higher priority, so that
the movie streaming is not disrupted by the traffic of the other devices on the network.
From the
Advanced
menu on the bar on the top of the page, click
QoS Engine
.
To assign a priority level to a device, drag the device card from the
Connected Clients
list over an empty slot and release the mouse button. The card will remain in the
slot. If you want to remove a priority assignment from a device and return it to the
Connected Clients
list, click the cross icon in the top right corner of the device card.

Save
when you are done.

Section 3 - Configuration
Firewall Settings
Enable or disable Demilitarized Zone (DMZ). Enabling this feature
creates a subnetwork that can be used to expose a single computer
to the Internet for applications that do not run well behind the router.
This may expose the computer to
a variety of security risks and is
not recommended.
If you enabled DMZ, enter the
IP Address
of the client you wish to
expose, or select a
Computer Name
from the drop-down menu.
Click to enable Stateful Packet Inspection (SPI) to help prevent cyber
attacks. This technique validates that the traffic passing through the
session conforms to the protocol.
Click to enable
Anti-Spoof Checking
, which will protect your
network from certain kinds of “spoofing” attacks.
Click to enable
IPv6 Simple Security
, which will provide simple
security capabilities for a local-area IPv6 network.
Click to enable
IPv6 Ingress Filtering
, which is a technique used to
make sure incoming packets originate from the networks they claim
to be from (prevents source address spoofing).

Click to enable
PPTP
, which will allow multiple machines on the
LAN to connect to their corporate network using the PPTP protocol.
Enable to allow multiple VPN clients to connect to their corporate
network using IPSec. Some VPN clients support traversal of IPSec
through NAT. This Application Level Gateway (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.
Check with the system administrator of your corporate network to
find out whether your VPN client supports NAT traversal.
Enable to allow applications that use Real Time Streaming Protocol
(RTSP) to receive streaming media from the Internet.
Enable to allow 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
Application Level Gateway (ALG) may interfere with the operation of
such devices. If you are having trouble making VoIP calls, try turning
this ALG off.
