You need to set up a VPN to access a corporate server in either of the following
two situations:
• Your company's wireless local area network (LAN) is located outside the firewall.
• Your company's wireless LAN is located inside the firewall, but you are trying to
access 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 to
access the corporate network. If you need a VPN, you must purchase and install a
third-party VPN client to use this feature.

for details.
2. Go to Applications
3. Select VPN.
