Security > VPN
A Virtual Private Network (VPN) is a connection between two endpoints in different
networks that allows private data to be sent securely over public networks or other
private networks. This is accomplished by creating a "VPN tunnel." A VPN tunnel
connects the two PCs or networks and allows data to be transmitted over the
Internet as if it were on a private network. The VPN tunnel uses IPsec to encrypt the
data sent between the two endpoints and encapsulate the data within a normal
Ethernet/IP frame, allowing the data to pass between networks securely and
seamlessly.
A VPN provides a cost-effective and more secure alternative to using a private,
dedicated, leased line for a private network. Using industry standard encryption and
authentication techniques, an IPsec VPN creates a secure connection that operates as
if you were directly connected to your local private network.
For example, a VPN allows users to sit at home and connect to his/her employer's
corporate network and receive an IP address in their private network just as though
they were sitting in their office connected to their corporate LAN.
Select the VPN tab to open the Security VPN page.
Use this page to configure the VPN for your residential gateway.

– Perfect Forward Secrecy (PFS): If PFS is enabled, IKE Phase
2 negotiation will generate new key material for IP traffic
encryption and authentication. Note that both sides must
have PFS enabled.
– Pre-Shared Key: IKE uses the Pre-Shared Key to authenticate
the remote IKE peer. Both character and hexadecimal values
are acceptable in this field, e.g., "My_@123" or
"0x4d795f40313233". Note that both sides must use the same
Pre-Shared Key.

To use keyword and domain blocking
Keyword and Domain blocking allows you to restrict access to Internet sites by
blocking access to those sites based on a word or a text string contained in the URLs
used to access those Internet sites.
Domain blocking allows you to restrict access to Websites based on the site's Domain
Name. The Domain Name is the portion of the URL that precedes the familiar .COM,
.ORG, or .GOV extension.
Keyword blocking allows you to block access to Internet sites based on a Keyword
or text string being present anywhere in the URL, not just in the Domain Name.
Note: The Domain blocking feature blocks access to any Domain in the Domain List.
It will also block Domains, any portion of which contains an exact match to entries in
the list.
For example, if you enter example.com as a Domain, any site that contains
―example.com‖ will be blocked. Generally, you do not want to include ―www.‖ in a
Domain Name since doing so limits the blocking to only the site that matches that
Domain Name exactly. For instance, if you enter www.example.com into the list,
only the one site that matches that name exactly will be blocked. Consequently, if
you do not include the ―www.,‖ then all sites within and associated with
―example.com‖ will be blocked.
Block Services
You can filter access to various applications accessed over the Internet, such as FTP
or telnet, by selecting up to two services to block in the Blocked Services section.
The Blocked Services drop-down menu offers a choice of preset applications. If you
select a preset application, its port numbers and protocol are displayed and cannot

Field Description
WPA
Security for Personal Networks - WPA or WPA2 Personal Modes
Wi-Fi Protected Access (WPA) is a more secure wireless technology
than WEP. WPA can be used for both Enterprise (corporate
applications) and Personal (home network) wireless networks. We
strongly recommend that you select either WPA-Personal or
WPA2-Personal as the security mode for your home network,
depending on which mode is supported by the wireless adapter in
your PC or wireless clients.
WPA-Personal (aka WPA-PSK or WPA-Pre-Shared Key), provides
a more secure wireless network that WEP. WPA-Personal
introduces TKIP user authentication and stronger encryption keys
than WEP.
WPA2-Personal (aka WPA2-PSK or WPA2-Pre-Shared Key)
provides the most secure standards-based wireless networking.
WPA2-Personal incorporates AES (Advanced Encryption Standard)
for data transmission.
Note: Not all wireless adapters support WPA2. WPA is supported
across a wider range of devices. Whether you use WPA or WPA2,
make sure to use a ―strong‖ passphrase. A strong passphrase is a
string of random characters at least 21 characters in length.

Configure Wireless Settings
Beacon Interval
The Beacon Interval value indicates the frequency interval of the
beacon. A beacon is a packet broadcast by the device to
synchronize the wireless network.
(Default: 100 msec, Range: 20-1000)
DTIM Interval
The Delivery Traffic Indication Message (DTIM) indicates the
interval between Broadcasts/Multicast transmissions. DTIM field
is a countdown field informing clients of the next window for
listening to broadcast and multicast messages. When the device
has buffered broadcast or multicast messages for associated
clients, it sends the next DTIM with a DTIM Interval value. Its
clients hear the beacons and awaken to receive the broadcast and
multicast messages.
(Default: 1, Range: 1-255)
Fragmentation Threshold
The fragmentation threshold value specifies the maximum size for
a packet before data is fragmented into multiple packets. If you
experience a high packet error rate, you may slightly increase the
Fragmentation Threshold. Setting the Fragmentation Threshold
too low may result in poor network performance. Only minor
reduction of the default value is recommended. In most cases, it
should remain at its default value of 2346.
RTS Threshold
The RTS Threshold determines at what packet size beyond which
the ready to send/clear to send (RTS/CTS) mechanism is invoked.
Should you encounter inconsistent data flow, only minor
reduction of the default value, 2346, is recommended. If a network
packet is smaller than the preset RTS Threshold size, the RTS/CTS
mechanism will not be enabled. The device sends Request to Send
(RTS) frames to a particular receiving station and negotiates the
sending of a data frame. After receiving an RTS, the wireless
station responds with a Clear to Send (CTS) frame to acknowledge
the right to begin transmission. The RTS Threshold value should
remain at its default value of 2347.
