How to get AC3200 (C7800) to not respond to probe attacks
I am having constant probe attacks to my cable-modem-router. A few of them are quite persistent. See below: [DoS attack: UDP Scan] from source: 146.88.240.4, port 42325, Sat, Apr 02, 2022 22:51:...
"Is Respond to WAN pings enabled on the modem? There is a setting under Advanced Tab/Setup/WAN setup I believe..."
NO CHECK MARK IN:
Disable IPv4 Firewall Protection
Disable Port Scan and DoS Protection
Default DMZ Server
Respond to Ping on Internet Port
Disable SIP ALG
MTU Size (in bytes) 1500
Hi Kakusu,
Good day!
Welcome to NETGEAR Community!
Thank you for reaching out. We are sorry for not getting back to you immediately. With the DoS attacks on the modem, does it affect your internet connection? Also, can you DM us the screenshot of the Shields up showing the ports as well as your Modem logs so we can present this to our Engineering team?
Please do not hesitate to let me know if you need further assistance.
Regards,
Oliver
