天翼云搭建l2tp服务端，FSU客户端频繁掉线

业务需求：客户端需要通过l2tp协议和我方服务器进行通信，服务器通过安装配置了xl2tpd等工具实现了VPN功能，启动正常。

问题是，目前，客户端已经配置了1300个客户端链接了VPN服务器。但是，服务器显示，只链接400多个客户端，而且只能连接上400多个左右的客户端。排查未连接的客户端，配置正常，连接不上机器和账号的也不是固定，而是随机，可能连接上，可能连接不上，不稳定，但是总体连接在400-500之间，期望是所有客户端能全部连接上Vpn服务器。

系统：

Linux Centos 7.5

实现方式：

xl2tpd+libreswan 

配置文件：

 Ipsec配置文件：

Xl2tpd配置文件：
