hello

My home router has 4 ethernet ports and an adsl port. I guess it is *technically* a router as the adsl has the public ip address and the ethernet ports have the private but to me its more of a switch with NAT. All 4 ethernet ports have the same ip address and they are non configurable. I can change the address of the switching element but this changes the ip for all 4 ports together.

Basically i want a *real* router where i can connect subnets to a switch and the switches to the router which has a different ip for each port.

What is this *real* kind of router called? What should i look out for?

Thanks
