Could an 871W handle firewalling, NAT, and NBAR?

[douglas.carmichael]

Could an 871W router easily handle firewalling, NAT, and NBAR on a typical broadband connection?

How much RAM/Flash would you recommend for those functions?

(Also, what's the difference in performance between an 870 series and a 1800/2800 series?)

Do the FCC and ETSI-compliant versions just have different images?
