　　openbsd服务器3块网卡

　　rl0 61.131.58.x 接公网

　　rl1 192.168.1.0/24 接内网段1

　　rl2 131.107.3.0/24 接内网段2

　　有些ip要24小时上网，有些ip限定8小时上网

　　写了两个脚本

　　shellpf1+pf1.conf（24小时上网）

　　shellpf2+pf2.conf(8小时上网)

　　shellpf1,shellpf2,pf1.conf,pf2.conf四个文件放在/etc/pf目录下

　　在crontab里定时执行,

　　文件/etc/pf/pf1.conf的配置如下:

　　ext_if="rl0" #接公网
192_if="rl1" #接内网段1
131_if="rl2" #接内网段2
