Re: need to identify device by port but only see internal
This is what a switch does - all ports are supported by one MAC address table.
My advice would be to go with device identification. But still, the devices are on the 'internal' port.
If you split the (hardware) switch into single ports, you cannot use the same network address on two or more ports. That is, to segment your LAN would mean to introduce several address spaces. No big thing but some effort required (address space, DHCP server, DNS and NTP on each 'internalX' port,...).
