CPG310, ssg5 or ???

I need to replace the firewal/router at our small office with something that can handle wireless properly. The catch is that we have 5 external IP addresses, and we use 2 of them currently (one for NATed clients, one for a webserver in a DMZ). The external connection isn't that fast (15mbit), but I'm having trouble finding a reliable firewall than can handle the multiple IP addresses, it's not usually a feature they tout.

I've used Junipers in the past, and although they are expensive, I know them and they've worked well, so the SSG5 is the expensive option. The CPG310 seems to do what I want at a much lower cost, although gigE would be nice, it's not a dealbreaker. For wireless draft-N would be nice, but G should be enough of an upgrade over current B to be good enough.

So what else should I consider that can handle multiple external IPs properly?

thanks

You're right that multiple WAN IPs are difficult to find in consumer-grade products. It doesn't help that manufacturers use different terms to describe the feature. One term commonly used is one-to-one NAT.

Anyway, the Linksys RV series support up to 10 one-to-one NAT mappings. See page 16 of the RV042 manual as an example. Add wireless by converting any wireless router to an AP and you're set.
