Network Address Translation (NAT) Configuration for Macintosh

By default, Network Address Translation (NAT) transparency is turned on. If you use a NAT device (i.e.,firewall, personal network snapway, Internet Connection Sharing device) and NAT transparency is turned off, you may need to turn NAT transparency on. One way to tell if you are behind a NAT device is to see if your computer's IP address is 10.x.x.x or 192.168.x.x.

To turn on NAT transparency:

1. Launch the VPNClient application. A window similar to the following will appear:
