In this example, you configure the J-series device to accept incoming calls over a NAT boundary. To do this, you can create an interface NAT address pool for dynamically allocating destination addresses. This differs from most configurations, where a source pool provides source addresses only. See Figure 110.

Interface NAT is when the source pool uses the same address as an interface IP address. You can use such address entries as destination addresses in policies, together with H.323, SIP, or other VoIP protocols, to support incoming calls.
To configure incoming calls using NAT, use either the J-Web or CLI Configuration editor.
