How to hide mac addresses from ISP?

Question

Network administration

Good day! The provider asked to hide all our poppies from him.
Its optics is included in the provider's switch DES-3200-10 and from there the lan cable goes to our 3810-28 and through other switches to our server where kerio is located, the question is: poppies or is it possible to do this on the switch itself?

Answer 1

The most adequate and crutchless method is to plug the optics into the router, and plug the switch into the router.
If this is not feasible, make crutches in the form of a separate wilan to the router, a separate wilan for your network, somehow switch it ...
