Connecting to a VPN If you want to use your Treo to access your corporate email account or other files on your corporate server, you may need to set up a virtual private network (VPN) on your Treo. A VPN enables you to log in to your corporate server through the company's firewall (security layer). You need a VPN client on your Treo 680 if your Treo 680 and your company's server are located on opposite sides of the firewall. Check with your company's system administrator to see if a VPN is required to access the corporate server. If a VPN is necessary, you must purchase and install a third-party VPN client on your Treo 680 to use this feature. TIP For information about third-party VPN client software, see the Palm Software Installation CD or visit www.palm.com/ mytreo680cingular. 212
