Disabling Security
If you choose not to use security with your WLAN, you need to disable it
on the CN30. By default, security is disabled on the CN30. Intermec rec-
ommends that you always set security in your network.
To disable security
1 For Network Authentication, choose Open.
2 For Data Encryption, choose Disabled.
Configuring a VPN
A virtual private network (VPN) is a private network that uses a public net-
work (Internet) to connect remote sites or users together. These networks
use encryption and other security mechanisms to ensure that only autho-
rized users can access the network and that data cannot be intercepted. The
CN30 uses the Microsoft CE .NET Remote Access Service (RAS) to set up
the VPN. You can configure the CN30 to use either Point-to- Point Tun-
neling Protocol (PPTP) or Layer Two Tunneling Protocol (L2TP).
PPTP is a network protocol that adds a security infrastructure for the trans-
fer of data from a remote CN30 to a private server, thus creating a VPN by
using TCP/IP-based data networks. Like PPTP, L2TP also uses Point-to-
Point Protocol (PPP) to encrypt data. L2TP uses Internet Protocol Security
Protocol (IPSec) to enable a more secure VPN client connection from your
CN30 to a remote server.
IPSec supports the following settings:
•
Public key certificates
• Pre-shared keys
Note: If you want to use L2TP and IPSec, they must be supported by the
corporate server.
To configure a VPN
1 From the Configuration Utility, select Communications > VPN.
2 Select Create New VPN.
3 Select VPN Name, type a VPN name, and then press Enter.
