One of my customer needs a solution for physically isolating the traffic between ports.
One of the interface ( in the port 2-5 range ) is connected to the corporate network,
another one to a broadband router and the third one to a printer. The idea is to see that
individually , both the internet and corporate interfaces can send / receive packets to /from
the printer interface , but the two interfaces can't exchange packets between themselves.
Is there anyway this can be done with firewall alone ? or does it need VLAN ?
