VPN Network Configuration Example

(Connecting to MAXCS with VPN)
Figure 2. MAXCS with VPN
In a multi-site configuration, VPN can be used to provide a secured tunnel between the
remote sites and the corporate site.
Figure 2 shows a network layout in which there are two private networks, the corporate
LAN and branch office LAN. The VPN tunnel connects the two private networks such that
the two networks access each other with a private IP address.
In the corporate network, MAXCS is installed on a host with private IP address
192.168.1.2.
Both Router 1 and Router 2 are VPN-capable and compatible with each other. (It is
recommended that the routers come from same vendor.) A VPN tunnel exists between
these two routers. The local IP phones—IP Phone 1 and IP Phone 2—directly connect to
the corporate network with private IP address 192.168.1.100 and 192.168.1.101. And
the three remote IP phones—IP Phone 3, IP Phone 4 and IP Phone 5—connect to the
branch office network with private IP addresses 192.168.2.100, 192.168.2.101 and
192.168.2.102, respectively.
