The
Security
screen, shown in Figure 6-11, allows you to change the Router’s
security settings. You should change the factory default password, which is
admin
, to your own as soon as possible. All users who try to access the
Router’s web-based utility or Setup Wizard will be prompted for the Router’s
password.
Router Password
The new Password must not exceed 32 characters in length
and must not include any spaces. Enter the new Password in the second field to
confirm it.
VPN Pass-Through
Virtual Private Networking (VPN) is typically used for
work-related networking. For VPN tunnels, the Router supports IPSec Pass-
Through and PPTP Pass-Through.
IPSec
- Internet Protocol Security (IPSec) is a suite of protocols used to
implement secure exchange of packets at the IP layer. To allow IPSec tun-
nels to pass through the Router, IPSec Pass-Through is enabled by default.
To disable IPSec Pass-Through, uncheck the box next to
IPSec
.
L2TP
- Layer Two Tunneling Protocol is an extension of the Point-to-Point
Tunneling Protocol (PPTP) used by to enable the operation of a virtual pri-
vate network (VPN) over the Internet.

Default Transmit Key
Select which WEP key (1-4) will be used when the
Router sends data. Make sure the receiver is using the same key.
WEP Encryption
Keys 1-4 offer 64-bit or 128-bit encryption; select the type
of encryption you want from the drop-down box. To disable WEP Encryption,
select
Disable
.
Passphrase
Instead of manually entering WEP keys, you can enter a
Passphrase. This Passphrase is used to generate one or more WEP keys. It is
case-sensitive and should not be longer than 16 alphanumeric characters. This
Passphrase function is compatible with Linksys wireless products only. [If you
want to communicate with non-Linksys wireless products, enter the WEP
key(s) manually on the non-Linksys wireless products.] After you enter the
Passphrase, click the
Generate
button to create WEP keys.
Keys 1-4
WEP keys enable you to create an encryption scheme for wireless
LAN transmissions. Manually enter a set of values. (Do not leave a key field
blank, and do not enter all zeroes. These are not valid key values.) Keys 1-4
offer 64-bit or 128-bit encryption.
If you are using 64-bit WEP encryption, then the key must be exactly 10 hexa-
decimal characters in length. If you are using 128-bit WEP encryption, then the
key must be exactly 26 hexadecimal characters in length. Valid hexadecimal
characters are “0”-“9” and “A”-“F”.
Check all the values, and click the
Apply
button to save your 2.4GHz, Wireless-
G WEP settings.
