FireHOL a simple yet powerful way to configure stateful
iptables firewalls. It can be used for almost any purpose,
including control of any number of internal/external/virtual
interfaces, control of any combination of routed traffic, setting
up DMZ routers and servers, and all kinds of NAT. It provides
strong protection (flooding, spoofing, etc.), transparent caches,
source MAC verification, blacklists, whitelists, and more. Its goal
is to be completely abstracted and powerful but also easy to use,
audit, and understand.
