Классический вопрос: тебе шашечки или ехать? Хотя на самом деле
вся разница в терминологии, а не в технологии. Вот тебе цитата
из того же howto:
4.8. Magic Hidden Within NAT; Application Proxies
Since ipnat provides a method to rewrite packets as
they traverse the firewall, it becomes a convenient place to
build in some application level proxies to make up for well
known deficiencies of that application and typical fire-
walls. For example; FTP. We can make our firewall pay
attention to the packets going across it and when it notices
that it's dealing with an Active FTP session, it can write
itself some temporary rules, much like what happens with
keep state, so that the FTP data connection works.
Hу и чем это отличается от stateful inspection? Hе в названии
ведь дело.
