Block IP from modem
Aug 16, 2018 10:21PM PDT

Is it possible to block a specific IP address from accessing your modem? I have a Motorola MB 7420 and want to block a device from accessing it. I understand how to block it from a router but the device can still be plugged directly into the modem and access the internet.

That depends on the modem. Check the user manual.

But it seems quite unlikely. Modems aren't smart enough, they only handle bits and waves, not IP-addresses.
