下载xl2tpd-1.3.1.tar.gz

tar zxvf xl2tpd-1.3.1.tar.gz

cd xl2tpd-1.3.1

在Makefile第121行插入-static，使其链接静态库编译

make CC=mips-linux-gcc

将xl2tpd 和 xl2tpd-control下载到板子上的/usr/sbin

mkdir -p /var/run/xl2tpd

mkdir /etc/xl2tpd

L2TP服务器

cd /etc/xl2tpd

vi xl2tpd.conf 写入

[lns default]

ip range = 192.168.10.128-192.168.10.254

local ip = 192.168.10.99

require chap = yes

refuse pap = yes

require authentication = yes

name = LinuxVPNserver

ppp debug = yes

cd /etc/ppp

vi chap-secrets 写入

user_l2tp LinuxVPNserver password_l2tp *

启动xl2tpd: xl2tpd -D

L2TP客户端

cd /etc/xl2tpd

vi xl2tpd.conf 写入

[lac testvpn]

lns = server_ip        #服务器ip

pppoptfile = /etc/ppp/peers/test.l2tpd

ppp debug = yes

cd /etc/ppp/peers/

vi test.l2tpd 写入

user "user_l2tp"

password "password_l2tp"

启动xl2tpd: xl2tpd

开始拨号：echo 'c testvpn' > /var/run/xl2tpd/l2tp-control

断开连接：echo 'd testvpn' > /var/run/xl2tpd/l2tp-control
