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:...
I am still looking for the ability to make the C7800 NOT respond to any port probes.
GRC shields up responds with the ports being closed but NOT STEALTH. The DOS reporting is incidental. I am not asking how to prevent the router from reporting these...
Even during the GRC scans it reports port probing in the logs. So I would like it if GRC reports STEALTH and not just closed.
I have responded to the commenters and apparently it's not posting it publicly... which is fine. I am still curious if this modem even has the ability that I am asking for. The rented cable modem had that ability.
Is Respond to WAN pings enabled on the modem? There is a setting under Advanced Tab/Setup/WAN setup I believe...
See if there is anything hidden here:

The R7800 has settings, although some, like enabling Telnet, have been removed in later firmware.
