A proxy firewall doesn't need to have IP routing capabilities (eg.
forwarding packet between interfaces). And a proxy firewall is definietly
a firewall. (some people doesn't call packet filters as firewalls, that's
true, they mean a proxy under the term: firewall)

Why does IP routing is so important if you want to build a packet filter?
The goal is to have the ability to deny or allow packets through the
device.
