We are moving into a new building. Each floor will have its own subnet. I am trying to determine what routers I should use. My boss wants to connect each floor and provide redundant ethernet lines to provide more throughput without going to fiber. (copper is already installed). To accomplish this we would need to have at least four routable network ports on each router. I was thinking that a 2811 would work since my boss would also like to provide stateful inspection and a vpn between floors since wire is run in a non-secure location.
What router can I use that would provide multiple ethernet redundant links between floors while providing firewall and VPN capabilities between these devices?
