1.4.4.2 Network Address Translation (NAT) Support
The below illustrates the supported NAT architecture.
Figure 1-2: NAT Functioning
The gateway uses NAT on the WAN interface. To allow successful calls to the WAN, the
SIP must use the WAN IP address for signaling. To do this, set the SIP Local interface to
the WAN interface (refer to 'SIP Proxy & Registration ' on page 82).
Because NAT is always enabled on the WAN interface, packets from LAN to WAN are
masqueraded and assume the WAN IP address.
1.4.4.3 Multiple Routers Support
Multiple routers support is designed to assist the media gateway when it operates in a
multiple routers network.
To support multiple routers, you can configure multiple static routes. For a description on
adding or removing static routes, refer to Section 'Static Routes' on page 123.
