How do I block a device from being seen by the internet while still being visible to those devices o

[Aurigo]

I have a device which can be connected to with ease when Access Control for it is turned off.

When I go into Access Control(on mobile app as this feature is not available for some reason in the desktop browser control) and click the radio button to disable internet for it, those on the LAN lose connectivity to it.

How do I block a device from being seen by the internet while still being visible to those devices on the LAN?

I should be able to simply block devices from accessing the WAN. Where/how do I do this?

I could do this with ease on DDWrt or OpenWrt.

P.S. I have the RBK853 AX6000, not the RBK53 AC3000, but your system doesn't list what I have and won't let me put my actual model in the model field.

P.P.S. If the user antinode feels like commenting. Don't. I don't want to hear anything from you ever again. Your advice to RTFM can go jump in a lake.

If the firmware supports it, go to Advanced -> Security -> Block Services. Enter the IP address and the full range of ports from 1 to 65535 and choose both protocols (tcp & udp). This will block Internet access to the device but it will be accessible on the LAN to others.

PS. It's best to set a reserved DHCP IP address for this device

   What, exactly, do you think that "Access Control" does?  I shun
Netgear-supplied apps, so I know nothing, but the usual definition of
"Access Control" refers to access to the _router_, not access to the
Internet.  If you block the printer's access to the router, then I would
not be amazed when other devices on your LAN can't talk to the printer.

   Still mysteries.

   Still true.

   Already answered.  Whether the procedure meets your criterion of
"simply" is unknown to me.

   _Why_ you're trying to do any of this also remains a mystery.

   What, exactly, is "this"?  Block incoming connections to the printer,
or block outgoing connections from the printer?

   Different firmware is different.

   I decline to accept responsibility for your determination to remain
ignorant.

   "Already answered" twice now.  Whether that's enough is yet another
mystery.
