Note: The public IP address is the same as the router's Local WAN IP address if Address Translation (NAT) is 
enabled on your router, or if your router is configured for a Numbered inter face. If NAT is not enabled, and your

Local WAN IP address is assigned to you dynamically, check the Quick View menu of your routers console 
screen for the current WAN IP address.

Workstation version 4.0 or Windows NT Ser ver version 4.0. Typically, only one VPN is installed on a PPTP 
client.
