问一个虚拟机连vpn的问题

有一台主机是windows，virtualbox虚拟了一台centos，完了得在centos里连vpn到办公内网去，用pptpsetup连接。虚拟机用的桥接模式。因为密码是动态的，我就这样连

 pptpsetup --create sinavpn --server ip  --username username --encrypt --start 

但是有LCP: timeout sending Config-Requests问题，我google看到要加载ip_nat_pptp，加载了还是这样。

因为连进去也是用终端，而且在vpn下p2p之类都不能用，所以才有这个需求。

Re: 问一个虚拟机连vpn的问题

感谢啊！ 整了很久原来是这个原因，其实我拨号到其他的pptp的server 没用用到这个东西的！
