xl2tp客户端:https://blog.csdn.net/loomz/article/details/52955267

配置完客户端要加路由....???


最新的为https://www.iteye.com/blog/haoningabc-2480610

2018年2月14日更新:
aws的ip为172.31.26.41

iptables -t nat -A POSTROUTING -s 172.31.26.0/24  -o eth0  -j MASQUERADE
然后按照
http://blog.csdn.net/kitvv/article/details/50696585
操作
psk的那个secure文件改成
13.115.181.153 %any: PSK "haha"

参考
http://www.esojourn.org/blog/post/setup-l2tp-vpn-server-with-ipsec-in-centos6.php?page=2&part=1
使用xl2tp和ipsec,ppp让iphone和mac上网
注意的地方
1.尽量用新版本
2.配置的vpn用户名密码要是系统能登录的
3.http://pkgs.org/centos-7/nux-dextop-x86_64/xl2tpd-1.3.6-2.el7.nux.x86_64.rpm.html
下载对应的系统对应的rpm包 xl2tpd
rpm -ivh xl2tpd-1.3.6-8.el7.x86_64.rpm
4.yum install ppp openswan
openswan就是ipsec
5.我linode的ip是106.187.44.20,要替换下面的ip到你的ip

[root@localhost ~]# cat /etc/xl2tpd/xl2tpd.conf
;
; This is a minimal sample xl2tpd configuration file for use
; with L2TP over IPsec.
;
; The idea is to provide an L2TP daemon to which remote Windows L2TP/IPsec
; clients connect. In this example, the internal (protected) network 
; is 192.168.1.0/24.  A special IP range within this network is reserved
; for the remote clients: 192.168.1.128/25
; (i.e. 192.168.1.128 ... 192.168.1.254)
;
; The listen-addr parameter can be used if you want to bind the L2TP daemon
; to a specific IP address instead of to all interfaces. For instance,
; you could bind it to the interface of the internal LAN (e.g. 192.168.1.98
; in the example below). Yet another IP address (local ip, e.g. 192.168.1.99)
; will be used by xl2tpd as its address on pppX interfaces.

  修改/etc/ssh/sshd-config文件.
将其中的PermitRootLogin no修改为yes
PubkeyAuthentication yes修改为no
