The 2210 is a router that is doing NAT with a stateful
firewall.  It will (assuming it's not too buggy) prevent
outside access to your network.

If you buy a second router (e.g. a Linksys or DLink), you'll
just be duplicating the NAT/firewall/routing functions in the
2210. You can do that if you want.  I used to run a two layer
NAT setup with a Cisco 678 DSL modem (configure to forward all
TCP/UDP ports) and an OpenWRT gateway.  There were features I
needed that OpenWRT had that the Cisco didn't.

Unless there's something specific that you want to do that
isn't supported by the 2210 (or you're aware of deficiencies in
the 2210), I probably wouldn't bother adding a second firewall
box.
