Sanewall 1.1.2 发布，Linux 防火墙构建工具

Sanewall is a firewall builder for Linux that uses an elegant language abstracted to just the right level. This makes it powerful and easy to use, audit, and understand. It allows you to create very readable configurations even for complex stateful firewalls. Sanewall 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, all kinds of NAT, providing strong protection (flooding, spoofing, etc.), transparent caches, source MAC verification, blacklists, and whitelists. Newer versions abstract the differences between IPv4 and IPv6, allowing you to define a common set of rules for both, while permitting specific rules for each as you need. Sanewall is a fork of FireHOL and can make use of existing FireHOL configuration。

Release Notes: Fixes kernel version detection per 1.0.2. The configure script makes sanewall executable. The unconfigured sanewall.in issues a warning when it is run directly. The configure script now sets /usr/local/etc as the location for Sanewall to look in as well as store configuration files in if --sysconfdir is not given, solving bug 78. There is a switch to enable debug output. Handles domain names that refer to records that are IPv4, IPv6, or both. Fixes protection against direct use of /sbin/iptables and /sbin/ip6tables that was broken from 1.1.0
