I'm assuming the OP is trying to save money. A firewall with 5xGbe
interfaces is going to thousands of dollars. With Cisco you would be
looking at a ASA 5520, which only provides 4xGbe and 1x10/100. If you
just need to provide inter-vlan routing and a firewall for Internet
access a layer 3 switch and separate firewall would be best.
