1. WEP Encryption:
WEP (Wired Equivalent Privacy) is based on IEEE 802.11 standard
and uses the RC 4 encryption algorithm to encrypt data over the wireless network so as
to protect your data from unauthorized accesses or intruders. When connecting to a
WEP network, the user has to know a key that can be either 64-bit or 128 bit with ASCII
characters or hexadecimal characters.
Authentication:
There are two options available for authentication; these are,
“
Open
System
”
and
“
Share Key
”
. For more secure protection, you should choose
“
Share Key
”
option which requires wireless clients have the same key positions with the VoIP &
Wireless Residential Gateway.
WEP Encryption Length:
Select either 64-bit WEP or 128-bit WEP. 128-bit WEP
requires a longer key than 64-bit WEP. Your wireless clients must have the same WEP
encryption length as this Residential Gateway; otherwise, the connection will not be
established.
Key 1 ~ 4:
Enter values for Key 1 to Key 4 with either HEX or ASCII characters.
If you choose 64-bit WEP as your WEP encryption length, enter 5 ASCII characters or 10
hexadecimal characters (
“
0-9
”
,
“
A-F
”
) for each Key (1~4). If you choose 128-bit WEP,
enter 13 ASCII characters or 26 hexadecimal characters (
“
0-9
”
,
“
A-F
”
) fro each Key (1~4).
2. WPA:
WPA stands for Wi-Fi Protected Access and intends to improve the security
functions of WEP by using two security-enhanced types to encrypt data, these are: TKIP
(Temporal Key Integrity Protocol) and AES (Advanced Encryption Standard).

27
WPA Cipher Suite:
Select either
“
TKIP
”
or
“
AES
”
(AES is a stronger encryption
method than TKIP).
WPA Pre-Shared Key:
Enter the pre-shared key value which can be between 8 and 63
characters long or 64 HEX characters long. Symbols and spaces can also be used.
3. WPA2:
WPA2, based on 802.11i, provides stronger wireless security than WPA to protect
your network from malicious intruders.
WPA Cipher Suite:
Choose either TKIP or AES.
WPA Pre-Shared Key:
Enter the pre-shared key value which can be between 8 and 63
characters long or 64 HEX characters long. Symbols and spaces can also be used.
2.5.4 WLAN Access Policy
Select
WLAN Access Policy Setting
from the
Network Management
menu,
then
WLAN
Access Policy Setting
screen page appears.
Access Policy:
To disable Access Policy function or to select
“
Allow all
”
or
“
Reject all
”
accesses from the control list.
Access Control List:
Enter MAC addresses (with the AA:AA:AA:AA:AA:AA format) that you
would like to add to the access control list. A total of 50 MAC addresses can be added to the
access control list.
Insert to list:
Once you have entered a MAC address, press
“
Insert to list
”
to add it to the
Page 28 / 91
28
list.
Delete from list:
Select a MAC address from the access control list and press
“
Delete from
list
”
to remove it from the list.
2.5.5 Static Route
The Residential Gateway uses IP or Host name to communicate with management
computers, for example using HTTP, telnet, SSH, or SNMP. Using IP static routes allows the
Residential Gateway to respond to remote management stations that are not reachable
through the default gateway, for example when sending SNMP traps or using ping packets
to test IP connectivity.
Select
Static Route
from the
Network Management
menu,
then
Static Route
screen page
appears.
Enable:
Tick the checkbox to turn on this static route rule.
Type:
Specify the Type to be used with the Residential Gateway IP address.
The types
available are listed in the pull-down menu with following options
–
NET (IP address), Host
(Host name).
Target:
Specify the IP network address or Host name of the final destination. Routing is
always based on network number.
Netmask:
Select the subnet mask for this destination from the pull-down menu.
Gateway:
Specify the default gateway IP address.
Action:
Insert - To insert a new static route to the Residential Gateway.
Change - To
modify the current static route setting.

2.5.6 NAT
Network Address Translation (NAT) allows the translation of an Internet protocol address
used within one network (for example a private IP address used in a local network) to a
different IP address known within another network (for example a public IP address used on
the Internet).
Select
NAT
from the
Network Management
menu, then the
NAT
screen page appears as
follows.
NAT Setting
Network Address Translation:
If you would like to activate NAT function, tick the enable
checkbox.
A
DMZ (Demilitarized Zone)
host is a computer without the protection of the firewall.
If you
have a client PC that cannot run Internet applications properly from the Residential Gateway,
you can set the client up for unrestricted Internet access. Adding a client to the DMZ
(Demilitarized Zone) may expose your local network to a variety of security risks.
Therefore,
enable this function when necessary.
DMZ:
Enable DMZ if checked.
DMZ LAN IP:
Enter the IP address that you would like to open all ports to.
DDOS Protection:
Tick the checkbox to enable Residential Gateway to detect SYN flooding
attacks. By default, this function is disabled which makes your device vulnerable to attacks.
To prevent your Residential Gateway from open malicious attacks, you should enable DDoS
Protection manually.
Detection Frequency:
Specify the frequency of attack requests to Residential Gateway.
When Residential Gateway detects malicious SYN attacks, it will clear streams occupied by
the source host.

Virtual Server Mapping
Virtual Server is used to set up public services on your network. When users from the
Internet make certain requests on your network, the Residential Gateway can forward those
requests to computers to handle the requests. For example, when you set the port number
80 (HTTP) to be forwarded to IP Address 192.168.1.2, all HTTP requests from outside users
will be forwarded to 192.168.1.2. You may use this function to establish a Web server or
FTP server via an IP Gateway. Be sure that you enter a valid IP Address. (You may need to
establish a static IP address in order to properly run an Internet server.)
For added security, Internet users can communicate with the server, but they will not
actually be connected. The packets will simply be forwarded through the Residential
Gateway.
Enable:
Tick the checkbox to enable this rule.
WAN Port:
Specify the WAN port number (1~65535).
Protocol:
Choose TCP, UDP or Both as your desired protocol.
LAN IP:
Specify the LAN IP - 192.168.0.xxx, where xxx is editable.
LAN Port:
Specify the port LAN port number (1~65535).
Action:
Insert- To insert a new Virtual Server setting to the Residential Gateway. Change-
To modify the current setting.
Port Trigger
Enable:
Tick the checkbox to enable this rule.
Trigger Port:
Enter the port number used by the application to establish an open service
port.
Trigger Type:
Choose either TCP or UDP.
Public Port:
Enter the port number to be allowed to pass through when trigger packets are
detected.
Public Type:
Choose either TCP or UDP.
Action:
Insert - To add a new port trigger to the Residential Gateway. Change - To modify
the current setting.
