VPN
What is VPN?
If you want to use your device to access files on your company’s servers,
you may need to set up a VPN (virtual private network). You can do this
using the VPN application. VPN enables you to log in to your corporate
server through the company’s firewall (security layer). You need to set up
a VPN to access a corporate server in any of the following situations:
• Your company’s wireless local area network (LAN) is outside the
firewall.
• Your company’s wireless LAN is inside the firewall, but you are
accessing the network from outside the firewall (for example, from a
public location or at home).
Check with your company’s system administrator to see if a VPN is
required for accessing the corporate network.
Add a VPNC VPN profile
VPNC is a Cisco-compatible IPSEC client.
BEFORE YOU BEGIN Get the following information from your system
administrator:
• Profile name
• VPN server
• Username and password
• Group ID
• Group secret
• Domain
• Dead peer detection setting: When selected, if no VPN traffic is
received for five minutes, the client checks to see if the VPN server is
still available.
• Encryption method: Secure, Weak, None: Secure forces the client to
use more secure AES or 3DES algorithms. Weak allows the weaker
1DES algorithm. Strong encryption may still be used, depending on
what the VPN server decides. None enables no encryption. Encryption
is not disabled and may still be used, depending on the VPN server.
With the None option, the VPN profile is simply allowed to use no
encryption.
• NAT traversal method: Cisco-UDP, NAT-T (always), NAT-T (auto-detect),
or Disabled
