Getting Bombed With DDos Attacks
Since switching to a CAX30 from a C7000v2 a month ago, as noted in the subject headline, Norton has blocked them effectively. This one was the most recent, and the IP address is Comcast in Burlington, VT. Comcast security has been notified.

ioned attacks every day(I check security logs).

Will need to keep in contact with the ISP for that IP address.
CAX30 is just reporting what's happening. Hopefully the ISP can figure it out.
Thx. I keep getting some attacks from different IP addresses, check the addresses via iplocation.com, and they all belong to Digital Ocean. I contact them and get a reply, "We'll tell our customers to stop"
Might ask the ISP to change the WAN IP address as well.
The firewall on the CAX is working. Just the logs are reporting what is happening is all.

Is that list of "attacks" from:
- The CAX30 log file, or
- From Norton on a PC?
CAX log.
Thanks. As FURRYe38 pointed out, it is not Norton that is detecting these "attacks". Netgear routers do not accept connection attempts unless the owner has specifically defined ports to "forward" to specific devices on the local network.
The CAX30 has a feature that can make entries in the router log file when its software "detects" what it considers to be an "attack". On my RBR50 there is an option:
This option controls whether these events are recorded in the log. (It does not affect whether the router accepts connections or not).
Several users have posted recently that when they replace an older "R-series" Netgear router with a newer model, the log suddenly started filling up with these "attacks". The simple fact is that any device connected to the internet will attract connection attempts. They cannot be stopped. (Just as a mailbox will receive "junk mail" and a telephone will receive marketing calls.) The R7000 did not fill up the log file with these reports, and the CAX30 does. Your choice is whether to look at them or not.
sorry about the typo. should be "C7000" rather than "R7000".
Thanks to all who replied. ;^)
