1、安装mpd(都说mpd对windows支持最好)，很简单

cd /usr/local/ports/net/mpd/ make all install clean 2、配置/usr/local/etc/mpd/mpd.conf default:

load vpn vpn:

load client1

#load client2

client1:

new -i ng0 pptp1 pptp1

set ipcp ranges x.x.x.x/32 y.y.y.y1/32

load pptp_def client2:

new -i ng1 pptp2 pptp2

set ipcp ranges x.x.x.x/32 y.y.y.y2/32

load pptp_def pptp_def:

set iface disable on-demand

set iface enable proxy-arp

set iface idle 1800

set bundle enable multilink

set link yes acfcomp protocomp

set link no pap chap

set link enable chap

set link keep-alive 10 60

set link mtu 1460

set ipcp yes vjcomp

set ipcp dns x.x.x.y set bundle enable compression

set ccp yes mppc

set ccp yes mpp-e40

set ccp yes mpp-e128

set ccp yes mpp-stateless

open

3、配置/usr/local/etc/mpd/mpd.links pptp1:

set link type pptp

set pptp self 对外提供vpn服务的ip

set pptp enable incoming

set pptp disable originate

pptp2:

set link type pptp

set pptp self 对外提供vpn服务的ip set pptp enable incoming

set pptp disable originate 4、编写启动脚本/usr/local/etc/rc.d/mpd.sh case $1 in

start)

[ -x /usr/local/sbin/mpd ] &&

[ -f "/usr/local/etc/mpd/mpd.conf" ] &&

/usr/local/sbin/mpd -b &&

echo -n ' mpd'

;;

stop)

killall mpd && echo -n ' mpd'

;;

*)

echo "Usage: `basename $0` {start|stop}" <&2

exit 64

;;

esac

exit 0 5、编辑用户/口令文件 /usr/local/etc/mpd/mpd/secret 很简单，照着例子作

好了，现在要做的事做完了。在winxp上创建一个vpn连接，ok，搞定。嘿嘿，还有2个非常重要的点，第一个要将freebsd服务器设置成路由模式也就是说在/etc/rc.conf中gateway_enable="YES" 要加上（网上找的资料都没说着点，完全凭经验），否则不能通过vpn服务器访问内网的其他主机。第二，winxp的防火墙要关掉，为什么不知道，总之不关，就会出现间歇性大量掉包
