Determining the published IP address

Use the flowchart in the following figure to determine which card should be set as the published IP

address.

Figure 3 Selecting the Published IP address

The flowchart shown above makes reference to public and private IP addresses. The public and

private IP addresses are concepts relating to Network Address Translation (NAT). The decision

also depends on whether a Virtual Private Network (VPN) is enabled. For information about NAT

and VPN, refer to the Programming Operations Guide.

If you use IP telephones on the network, they must be set to have the IP address of the network

card they are connected to for their Default Gateway, and the Published IP address as the S1 IP

address. For more information about this, refer “Configuring the i20XX telephones to the system”

on page 47.
