keys.
Simply configure the Default Key to the one key that you will be using across your
network.
On the wireless clients, you can use the passphrase option, and client utility will generate the
same 4 keys – or you can manually type in the selected KEY that is configured on the Gateway.
For more security, you can use 128-bit WEP encryption.
To use this mode, click the [128 Bit
Encryption] option and the configuration section will be displayed.
You can manually enter in
the 26-digit hexadecimal key or use the passphrase option to generate random dynamic keys.
NOTE
: If you are having a difficult time getting the wireless connection up after enabling WEP –
please confirm that you have configured the SAME WEP key on both the Gateway and Client
card.
WPA-PSK
Select [WPA-PSK] from the [Encryption Type] drop down menu. Next, enter a passphrase value
between 8 and 63 characters in the [WPA Passphrase] field.
MAC Filtering
The Gateway can allow the wireless client stations to connect over a wireless connection in 2
different ways:
1.
By allowing all wireless stations access;
2.
Or by allowing only Trusted PCs.
To access the MAC Filtering configuration page, on the Side Navigation bar, click on [Wireless]
link and then click on the [MAC Filtering] link.

You can also configure a [Device Name] that is associated with a specific MAC address. In doing
this, you can easily recognize the computers that you are in your access list.
NOTE
: MAC filtering only applies to Wireless Clients.
NAT
Network Address Translation (NAT) allows multiple users at your local site to access the
Internet through a single public IP address.
Port Forwarding
The Gateway supports port forwarding that enables customers to host servers on their LAN.
You can configure this feature to redirect the external service request to the appropriate
internal server and port.
For example, if you are running a WEB server, you can configure all traffic on port 80 to be
redirected to the IP address of the WEB server running on your network.
To access the Port Forwarding configuration page, on the Side Navigation bar, click on [NAT]
link and then click on the [Port Forwarding] link.

This Port Forwarding function supports 2 types of Services:
•
Predefined Service
•
Customer Defined Service
Predefined Service
The Predefined Service option has a pull-down menu with several popular Service Applications,
such as HTTP (80), FTP (20/21), and AIM/ICQ (5190).
To configure Port Forwarding with a Predefined Service rule, follow the steps below:
1.
Select the [Service] that you want to have access through the firewall to your LAN from
the pull-down menu.
2.
Enter in the [LAN Server IP] for the LAN PC that is running this service or application
3.
You can also configure [Remote IPs] option to allow access to this specific port from
the WAN side. This can be configured for 3 different access types:
a.
Any IP Address [Any] – choose this option to allow access from any public IP
address.
b.
Single IP Address [Single Address] – choose this option to only allow access from
a single public IP address.
c.
IP Address Range [Address Range] – choose the option to only allow a range of
public IP addresses.

screen
Customer Defined Service Rule (Custom)
The Customer Defined Service section allows you to custom configure a Port Forwarding rule
with any Traffic type (TCP/UDP/TCP and UDP), Public Port, and Private Port.
To configure this custom option, please follow the steps below:
1.
Enter in a Description [Name] for this custom setting
2.
Configure the Traffic or Data [Type] that you want to forward.
The options are
TCP |
UDP | TCP/UDP.
3.
Set the [LAN Server IP] of the PC that you want this traffic/data redirected to
4.
You can also configure [Remote IPs] option to limit access to this specific port from the
WAN side. This can be configured for 3 different access types:
a.
Any IP Address [Any] – choose this option to allow access from any public IP
address.
b.
Single IP Address [Single Address] – choose this option to only allow access from
a single public IP address.
c.
IP Address Range [Address Range] – choose the option to only allow a range of
public IP addresses.
5.
Set the [Start Public Port] and [End Public Port] that this application will use on the
WAN (Internet) side.
The Gateway will listen for incoming traffic/data to its WAN IP on
these ports.
6.
Set the [Private Ports] that the Gateway will forward this traffic to on the LAN.
If
there is a range of ports, enter the starting private port in [Private Ports], select
[Enable Port Range] checkbox, and the Gateway will automatically calculate the end
private port.
The LAN PC server will listen for traffic/data on this/these ports.
Below is an example setting for a WEB server on an Internet connection, where port 80 is
blocked from the WAN side, but port 8000 is available.
Name:
Web Server
Type:
TCP
LAN Server IP:
192.168.0.100
Downloaded from
www.Manualslib.com
manuals search engine
Page 30 / 60
Remote IPs:
Any (allow access to any public IP)
Public Port:
8000
Private Port:
80
With this configuration, all HTTP (Web) TCP traffic on port 8000 from any IP Address from the
WAN side will be redirected through the firewall to the Internal Server (192.168.0.100) on port
80.
NOTE
: This configuration is useful because you don’t have to reconfigure your web server to
accept traffic on a different port, you can do this configuration on the Gateway.
FIREWALL
The Gateway provides a stateful inspection firewall (SPI), which is designed to protect against
Denial of Service (DoS) attacks. Its purpose is to allow a private local area network (LAN) to be
securely connected to the Internet. To provide a flexible solution, the firewall section has the
following features:
Firewall Enable/Disable
To access the Security Settings configuration page, on the Side Navigation bar, click on
[Firewall] link.
To enable this feature, check the [Enable Firewall Module] checkbox.
Access Control
The Access Control section allows the setting of two types of rules: enable access to services on
your
public LAN
network from the Internet or to block services on the
private LAN
from
accessing the Internet. Access Rules can be configured to a specific LAN IP Address or a range
of LAN IP Address’s.
To access the Access Control configuration page, on the Side Navigation bar, click on [Firewall]
link and then click on the [Access Control] link.
To enable this feature, check the [Enable Access Control] checkbox.
There are 2 sections in that can be configured for Access Control Rules.
The first section is used to configure the Access Rules for the Public LAN from the Internet.
These rules will enable services on the public LAN to be accessed by the Internet.
