A firewall does not require two interfaces, just two IP addresses. That's
what aliases are for; assigning multiple IPs to a single NIC. The only
time that a second interface would be required is if you're running an IP
Filter transparent bridged firewall in which the interfaces have no IPs at
all. See http://www.obfuscation.org/ipf/ipf-howto.html#TOC_48 for more
info.
