I have been trying to determine which CISCO model(s) will provide the solution for our configuration requirements using your website. I am having some difficulty. We are setting up access to a data center for 3 clients. They will each access a separate server. The servers should all be connected to the same router via Ethernet ports. The router will be connected to the Internet also through an Ethernet port. The client will VPN into their respective servers, each using a different IP address (3 ip addresses). We need to have bandwidth throttling using the client ip address. The setup must also have a firewall, act as a VPN server and also support IPSEC. I figure that a router/switch combo is what I need. What would you recommend?
