Ac1750 getting scanning warning from at&t modem

[teamzissou22]

I recently had at&t fiber installed and wanted to keep my netgear router for wifi and just use the ata&t gateway as a modem.

2-3 times a day i am getting a warning from the at&t app saying it is blocking a scanning attack from my router. Picture attached. At&t was no help and said someone is probably tapping into my router and I should switch back to their gateway. Any help? Something I should be worried about?

Its not scanning the router because the att router is blocking it. If it did get to the router, it might be blocked by the netgears own protection. 

Nothing to worry about.
