HOW TO share a VPN connection.

A VPN Connection is really just a special form of Dial-Up Networking connection and NAT32 can share that connection in the usual way. Simply establish the VPN Connection to your VPN Server and then configure NAT32 to use that connection as an Internet Interface. Be sure you configure the MTU of the connection correctly in the appropriate Interface Configuration dialog box. The correct value to use for PPTP-based VPN connections is 1454 bytes, but a value of 1400 bytes may be required in some cases.

The following changes to the Windows TCP/IP configuration on your machine take place when a VPN Connection is established:

Note that the above changes do not necessarily have any impact on NAT32, as NAT32 bypasses the Microsoft TCP/IP stack for all traffic it forwards to the Internet or to private machines. NAT32 can therefore continue to use the old default gateway if desired, and it can also reach all your private machines exactly as before.
