Our logs are going crazy with a few different attempts to login to the PPP service via radius, but radius denies because their PPP account is wrong.
In our case, this is probably somebody with our modem that set it up wrong. The problem is that I can only seem to track it via MAC address.
I want to disable these PPP calls from our routing processing them or even hitting our Radius, so I can clear the logs and also so our Radius server isn't hit with multiple requests every second.
How can I block this?
