Figure 4.1: Typical DSView 3 Software System Firewall Configuration
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.
