Orbi RBR50 suddenly getting [DoS Attack: ARP Attack]
Not sure what happened and hoping some can help. My Orbi RBR50 is getting a lot of messages similar to the ones shown below for some reason. What should i do? [DoS Attack: RST Scan] from source:...
i'm using a modem plus router (ZTE VDSL CPE ZXHN H168N)provided by the service provider call Netvigator. My router is connected to one of the LAN port of this router.
IF this is the case, if there is a built in router at the modem, This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT

Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktop
Thanks for the valuable dvice. i have ask the ISP for the access to their modem/router before but they refused to provide this information. I will try to ask them if they can set this for me instead then. Hopefully they are willing to assist.
