Has anyone implemented a 2800 series router with the firewall/vpn/nac capabilities? Is that built into the IOS by default, or are there different images based on the capabilities? The reason I ask is I'm looking at replacing our current, old 2610 and our current Checkpoint firewall, and it would make more sense to me if I could have a single appliance to cover the router and firewall capabilities. Any feedback would be appreciated.
