圖中的『3接口路由器』可以用WIN2K或LINUX系統(tǒng)啟動(dòng)IP轉(zhuǎn)發(fā)替代,。
3.OPENBSD網(wǎng)絡(luò)設(shè)置:
Fxp0: 192.168.0.100 Ne3: 192.168.1.100 Gateway: 192.168.0.1
4.PF規(guī)則:
# vi /etc/pf.conf
=================================================
if_isp1="fxp0"
if_isp2="ne3"
gw_isp1="192.168.0.1" gw_isp2="192.168.1.10"
block all
pass quick on lo0 all
pass in quick on $if_isp1 reply-to ( $if_isp1 $gw_isp1 ) proto{tcp,udp,icmp} to any keep state pass in quick on $if_isp2 reply-to ($if_isp2 $gw_isp2 ) proto {tcp,udp,icmp} to any keep state
pass out keep state
=================================================
為了試驗(yàn)方便,以上PF規(guī)則沒(méi)有對(duì)TCP/UDP等協(xié)議的端口進(jìn)行限制,。大家根據(jù)自己的實(shí)際情況修改一下即可,。為了方便控制PF的啟動(dòng)和關(guān)閉,下面列出我使用的一個(gè)SHELL腳步:
# vi /etc/rc.d/pf.sh
=================================================
#!/bin/sh
# made by llzqq
# pf startup scripts
#
case "$1" in
start)
if [ -f /etc/pf.conf ]; then /sbin/pfctl -e -f /etc/pf.conf
fi
stop)
/sbin/pfctl -F all
/sbin/pfctl -d
*)
echo "$0 start | stop"
esac
exit 0
