VPNs

A Virtual Private Network (VPN) is a secure network that uses public infrastructure and typically includes several Wide Area Network (WAN) components that may impact performance of the VPN.

Typically, two sites are connected in a VPN network using WANs and a router. This setup provides a secure network between the two sites, but processing is slow.

Several factors related to the network setup, including the DSView 3 software database replication schedule and methods of device access, can affect the speed of a multi-site VPN network. The trade-off must be made based on the network setup.
