Ethernet over Coax with Orbi RBK50

[mnspink]

I have some Dualcomm ethernet over coax adapters. https://www.amazon.com/Dualcomm-Ethernet-over-Adapters-DECA-100/

I had them working earlier, but with latest firmware (2...74 and now 2.1.2.18) I can't get them to work.  Orbi router sees them as a DoS Attack. 

Some of the potential denials from the log:

[DoS Attack: SYN/ACK Scan] from source: 111.13.101.208, port 80,

[DoS Attack: ARP Attack] from source: 192.168.1.19,

[DoS Attack: TCP/UDP Echo] from source: 209.249.181.21, port 123

Retried my Powerline boxes again since I can't get EoC to work.  The Powerlines have never worked since I got Orbi.

Still don't work, FYI.  Also think they are being rejected by Orbi router

I get the DoS blocks on 111.13.101.208 with no powerline adapters.  I'd look into what an ARP attack is, because 192.168.1.19 is something on your network, and my guess is its your powerline adapter.

The IP on my network was an iMac. 

Maybe it's not due to the router seeing a DoS attack, but neither EoC nor Powerline work with Orbi for me.
