VPDN or Virtual Private Dial-Up Networking is also another form of VPN connection. VPDN is base on Layer 2 tunneling technology (L2TP and PPTP) and it is a point-to-point tunneling protocol with port 1723 and GRE tunnel to encapsulate packets. VPDN required Microsoft client tool in order to dial to remote network. What are the benefits of using VPDN?

Disadvantage of Using VPDN (PPTP)

The disadvantage of using VPDN is it does not encrypt message traffic and the connection is vulnerable to attack by hackers.

However, it all depends on users requirements and preferences.
