Hi,
I have a case where the customer has a scope of public IP-addresses.
What i need to do is prevent that the IP-addresses only can be used by a specific physical port i a CRS.
i have attached a PDF to show what i need. Hopefully this is something that is quite easy to setup.

Best regards
Anders

Have a look at thw Switch ACL features on the CRS:

Thanks

It will hopefully let you do what you want with using the CPE, thus at wire speed.
