win7使用l2tp连接linux服务器问题

[FeiY_]

我按照网上教程配置了linux的服务器，使用的是xl2tpd
然后在用的我WIN7连接的时候出现了下面的错误


xl2tpd[4821]: control_finish: Peer requested tunnel 26 twice, ignoring second one.
xl2tpd[4821]: Connection established to 172.31.136.13, 1701. Local: 7224, Remote: 26 (ref=0/0). LNS session is 'default'

配置过的朋友应该能看出来上面的问题在哪了
客户端这里显示错误：“错误628:在连接完成前，连接被远程计算机终止.....”

请教配置过l2tp的高手给小弟指点一下 谢谢

不太看得出来具体的错误，但应该是认证问题。

由于认证问题，xl2tp终止了pppd（因为ppp协议是l2tp协议的基础之一）。
