Blocking DDNS

Due to Azure vWAN not responding well to two Meraki networks using the same IP (via FQDN), I need to have a fool proof way of stopping anyone in our IT department, accidentally or intentionally, 'daisy chaining' Meraki networks, which results in both MX's DDNS using the same internet IP.

 

I was hoping there would be a simple firewall rule I could using to stop any daisy chained MX from registering with DDNS, and hence resulting in stopping two DDNS addresses from two networks having the same IP.

 

Any help or advice appreciated, thank you.

Meraki support have confirmed that DDNS is part of the dashboard comms, so I will block that.

Block Dashboard communication completely? Or is there anything that can be blocked specifically for DDNS?
