how to block incoming connections by their IP address
I run several servers (FTP, Remote desktop,MySQL). Netbots are continually attempting to connect and login. Is there a way to block these INcoming IP addresses? I have already used Windows Firewall ...
For remote desktop, I do use non-standard ports for each of my machines. For my FTP server, I use passive connections, strong ID's & passwords. I will have to consider using an odd port for that too. It just bothers me that my CPU and OS have to handle these constant interrupts, thus slowing down my performance (although with my recently installed Intel 9700K, it isn't THAT bad anymore). I would think that it should not be that hard for the firmware to store a list of IP's (defined by me in the Security section of the interface) to be ignored. I could extract then from the log and copy/paste them as needed. Yes, I CAN do that with the OS's firewall, but again, that's CPU and I/O interruptions.

If you're sufficiently annoyed by the break-in attempts. I run an
exposed FTP server, and I'd estimate that I typically see a few serious
password-guessing attempts per month, but seldom repeated attacks from
one remote address.

I don't see much of a resource drain. Or "constant" anything.

You could be right, but Netgear firmware for consumer-grade routers
is chronically buggy, so it might make very little sense to (or for)
Netgear to invest resources in a feature which will be used by such a
small fraction of its customers, when it has so many more important
problems to solve. Like deciding which existing features to remove, in
order to make room for new, revenue-generating features. One of which
this wouldn't be.
Beside which, I wouldn't bet on their ability to implement it
correctly.
Yet another potential waste of time and effort:

Yes, I see your point about expense to add features. I worked at IBM and saw that happen all the time. Bottom-line management. But my Nighthawk R7000 has worked flawessly and has excellent features.
PS. By "constant", I mean that my system is being probed every 3-8 seconds, all day. Hitting my web, FTP, Minecraft and MySql ports (all renumbered from originals, of course).
