freebsd9.1 防火墻不生效問題求解 ipfw.rule

netsnails

個(gè)人pc機(jī)器安裝freebsd9.0  服務(wù)器正常運(yùn)行 跑著wordpress博客 ，我添加一條指令
ipfw add 10001 deny all from 192.168.1.6 to any

ipfw show 顯示這條規(guī)則 ，防火墻正常運(yùn)行
本人用192.168.1.6這臺(tái)電腦還是可以訪問服務(wù)器，也可操作， 求指點(diǎn)




/etc/ipfw.rule文件內(nèi)容如下

#!/bin/sh

#ipfw pipe 2 config bw 300Kbit/s queue 20

# deny and log everything
$IPF 500 deny log all from any to any


開機(jī)啟動(dòng)文件rc.conf 防火墻文件如下

firewall_enable="YES"
firewall_script="/etc/ipfw.rule"
firewall_quiet="NO"
#open ipfw function

ipfw list 貼完整的信息出來(lái)看下！直接貼配置看不出你系統(tǒng)實(shí)際生效的規(guī)則是什么樣子的！有可能是在你的10001 rule前面有其他的rule給pass了！
