VPN Settings:
A virtual private network (VPN) is a method of computer networking---typically using the
public internet---that allows users to privately share information between remote locations,
or between a remote location and a business' home network. A VPN can provide secure
information transport by authenticating users, and encrypting data to prevent unauthorized
persons from reading the information transmitted. The VPN can be used to send any kind
of network traffic securely. ZX20 Series IP PBX support N2N and L2TP.
