9.16.10 L2TP

The Layer 2 Tunneling Protocol (L2TP) works at layer 2 (the data link layer) to tunnel network traffic
between two peers over another network (like the Internet). In L2TP VPN, an IPSec VPN tunnel is
established first and then an L2TP tunnel is built inside it.
L2TP VPN lets remote users use the L2TP and IPSec client software included with their computers'
operating systems to securely connect to the network behind the NR2301. The remote users do not need
their own IPSec gateways or VPN client software.

9.16.11 WiFi Protected Setup (WPS)

Your NR2301 supports WiFi Protected Setup (WPS), which is an easy way to set up a secure wireless
network. WPS is an industry standard specification, defined by the WiFi Alliance.
WPS allows you to quickly set up a wireless network with strong security, without having to configure
security settings manually. Each WPS connection works between two devices. Both devices must
support WPS (check each device's documentation to make sure).
Depending on the devices you have, you can either press a button (on the device itself, or in its
configuration utility) or enter a PIN (a unique Personal Identification Number that allows one device to
authenticate the other) in each of the two devices. When WPS is activated on a device, it has two
minutes to find another device that also has WPS activated. Then, the two devices connect and set up
a secure network by themselves.
9.16.11.1 Push Button Configuration
WPS Push Button Configuration (PBC) is initiated by pressing a button on each WPS-enabled device, and
allowing them to connect automatically. You do not need to enter any information.
Not every WPS-enabled device has a physical WPS button. Some may have a WPS PBC button in their
configuration utilities instead of or in addition to the physical button.
Take the following steps to set up WPS using the button.
Ensure that the two devices you want to set up are within wireless range of one another.
