Having pointed out some details here, I'd say most of those
little commercial firewalls are not sufficient anyway.

I must admit I don't really know these blackboxes and therefore
I do not trust them anyway. 

My suggestion is to get a decent PC (or Sun), fit it with 
enough NICs and go build your own firewall with a BSD or
Linux, whatever your favorite is.

I've seen a firewall connecting four different networks, 
making NAT on one of them plus managing an IPSec-Tunnel and
being a VPN-Server as well. The machine was a P350 or 
something, 512 MB RAM and was running FreeBSD 4.x. 
Run like a charm.

Of course you need to know what you're doing, but you need
that with any firewall and IPFW isn't that difficult.

CU, Venty
