Don't use screenshots in Questions, publish capture files at Cloudshark or at any general-purpose file sharing service, and provide login-free links to them.

As one of the addresses is public and the other one, which changes to at a certain point, is a private one, I would expect that there is a NAT device between the capture point and the Internet and that the software of this device is broken.

As the screenshot does not show MAC addresses, nor does it show the UDP payload, it is impossible to say more.
