Currently I've got a cable modem connected to my firewall. The firewall is configured to drop traffic from subnets in Asia, China, etc.
I'd like to put a router in front of the firewall where the only job is to route everything but a blacklist. That will decrease load on my firewall overall, and add an additional layer.
What is the right Cisco device for this? When I look at the 1800 series they seem intended for WAN traffic, but as far as my local connection is concerned, it's ethernet <> ethernet. Mostly I need the ability to hold like 300k of routing entries.
