You might like to read the white paper on Watchguard's web site.

Why a Real Firewall Provides the Best Network Protection

Many small businesses mistakenly believe that low-end NAT devices with
or without stateful packet inspection (SPI) functionality provide the
same network protection as a true firewall. But these devices were not
built for security and leave networks open to attack. This paper
explains how NAT devices work, how firewalls are different, and why an
integrated firewall/VPN solution provides the best network protection
for small businesses, remote offices, and telecommuters.
