SPA122 TR-069 (TR69) Connection Request Behind a NAT

Hi Cisco,

 

We are deploying SPA122 behind a router and want to enable TR-069 connection requests to the SPA122 from our ACS server. The ACS server tries to reach out to the SPA122 IP listed in the below CWMP segment below (Device.ManagementServer.ConnectionRequestURL:http://192.168.0.254:8890/). This is not a publicly routed address so the ACS server can't get to this address and complete its connection request.

 

My question is: How can I get the SPA122 to detect it is behind a NAT and provide the public IP of the router instead (ex: Device.ManagementServer.ConnectionRequestURL:http://68.69.100.50:8890/)?

 

 

Here is an inform from the SPA122 where is updates its ConnectionRequestURL...
