There is Ubuntu 22.04 x64 LTS server with nftables installed on multi ethernet interfaces network card server.That is all interfaces are ethernet physical ones, not bridged.
On one of then 2 pon terminals with different macs are connected via a switch.
I need to deny access two ways: pon termibal <----> server on L2 by mac of the device.
For example today I need to be accessed pon termibnal withmac a1:b1:c1:d1:e1:f1.But tomorrow I want that this termibal wouldn' t be visible on the netwrk by L2 but would be visible other one with mac a4:b4:c4:d4:e4:f4.
How is it possible to release using nftables or other software ?
