VPN Tab
Wireless-N Gigabit Security Router with VPN
VPN Client Accounts
You can allow remote users to easily establish a VPN connection to your Router using the Linksys QuickVPN client
utility without using a compatible VPN Router with IPsec VPN settings. This is achieved by creating user accounts
on the Router and authenticate users through Username and Password. After creating user accounts, it will be
summarized in the table below.
For users using QuickVPN, it will first establish an SSL connection with remote Wireless Router to get
authenticated. Then QuickVPN will automatically negotiate IPsec settings with the remote Router. All the data
packets will be encrypted using IPsec thereafter.
The Wireless Router supports up to five Linksys QuickVPN clients by default. Additional QuickVPN Client licenses
can be purchased separately.
Username
. Enter the username using any combination of keyboard characters.
Password
. Enter the password you would like to assign to this user.
Re-enter to Confirm
. Retype the password to ensure that it has been entered correctly.
Allow User to Change Password
. This option determines whether the user is allowed to change their password.
VPN Client List Table
No
. Displays the user number.
Active
. When checked, the designated user can connect, otherwise the VPN client account is disabled.
Username
. Displays the username.
Edit
button. This button is used to modify the username, password, or toggle between whether the user is
allowed to change their password.
Remove
button. This button is used to delete a user account.

VPN Passthrough
This screen allows users to use their own VPN algorithms to connect to their remote Routers. The Wireless Router
will just pass the traffic through.
IPsec Passthrough
. Internet Protocol Security (IPsec) is a suite of protocols used to implement secure exchange
of packets at the IP layer. IPsec Passthrough is enabled by default to allow IPsec tunnels to pass through the
Router. To disable IPsec Passthrough, select
Disabled
.
PPTP Passthrough
. Point-to-Point Tunneling Protocol (PPTP) allows the Point-to-Point Protocol (PPP) to be
tunneled through an IP network. PPTP Passthrough is enabled by default. To disable PPTP Passthrough, select
Disabled
.
L2TP Passthrough
. Layer 2 Tunneling Protocol is the similar to PPP but allows Layer 2 and the PPP session to
terminate at different servers or locations. L2TP Passthrough is enabled by default. To disable L2TP Passthrough,
select
Disabled
.

QoS Tab
Wireless-N Gigabit Security Router with VPN
QoS Tab
QoS (Quality of Service) allows you to prioritize network traffic using either
Application-based
priority (such as
Web browsing applications, FTP applications, etc.) or
Port-based
priority, which allows you to assign priorities to
the four physical network ports. Higher priority traffic will be allocated more bandwidth, which results in lower
latency (or delay).
Application-based
The Application-based QoS controls priority differentiation for data packets between LAN (including WLAN) and
WAN ports. Application-based QoS is achieved by software running on the CPU so it cannot control traffic
between LANs that are switched directly by a hardware switch chipset.
Application-based QoS
. QoS (Quality of Service) is
disabled
by default. When enabled, this option allows you to
assign priority based on the application type.
Set Internet Bandwidth
. Enter approximate bandwidth number for your WAN connection. This will help the
software-based algorithm to allocate bandwidth to different priorities.
•
Select the desired option for each application: High priority, Medium priority, or Low priority.

FTP
TCP Port 20
FTP (File Transfer Protocol) is used for transferring files over the Internet.
HTTP

HTTP (HyperText Transfer Protocol) is used for browsing the Internet.
Telnet
TCP Port 23
Telnet is a client-server protocol used to communicate over a network or
the Internet.
SMTP
TCP Port 25
SMTP (Simple Mail Transfer Protocol) is used for sending e-mail.
POP3
TCP Port 110
POP3 (Post Office Protocol version 3) is used for retrieving e-mail.

IMPORTANT:
If you don’t assign different priorities to applications, there will be
no differentiation between different traffic types.

Port-based
Port-based QoS is implemented in hardware so it can achieve better throughput. It can only control traffic among
the four LAN ports.
LAN ports 1-4 can be assigned High, Medium, Normal, or Low priority. Lower priority traffic will be slowed down
to allow greater throughput for higher priority traffic.

Administration Tab
Management
Local Gateway Access
This configures the administrator user accounts to manage the Wireless Router through Web based Utility. Only

. Select a user to configure from the drop-down menu.
Gateway Username
. Enter the user name here.
Gateway Password
. Enter the password.
Re-enter to Confirm
. Retype the password in this field.

or write information from or to the device.
Device Name
. Enter a suitable name. This name will be used to identify this device, and will be displayed by your
