关于自动重连 about autoddvpn HOT 8 OPEN

你VPN主機是填寫hostname還是IP？

ip

暫時看不大出問題，不過我看到你的DDWRT版本是 SVN revision 
16214
建議試試看15xxx版本 or 14xxx版本試試看

我想知道autoddvpn是掉線重連，無限嘗試
還是嘗試n次後就不再重連了

然後就卡在
[INFO#19912] 25/Feb/2011:16:30:06 ALL DONE. Let's wait for VPN being connected.

這句了

reboot route就又連上了

DDWRT的PPTP client是自己會retry 
connect的，但是PPTP這個協議在DDWRT裡面我觀察比較容易不穩。

當你看到
ALL DONE. Let's wait for VPN being connected.
表示autoddvpn已經准備就緒，一旦pptp連上，取得ppp1這個device的
IP的時候，就會自動觸發vpnup.sh

但一旦VPN斷線，例如網路不穩等情況發生時，ppp1失去了IP,  
則就會觸發vpndown.sh

下次再自動播上，又會vpnup.sh ...

推究你的原因有可能是：
1. 你所在的網路環境跟PPTP VPN server之間網路不穩定
2. DDWRT自帶的PPTP client不穩定
3. DDWRT路由器不穩定

都有可能。

issue #34 和 #50 
都属于我在使用pptp+jffs时候出现的问题，换成openvpn就没有出�
��了。如果没有其它人回报这个问题，建议close

我总是停在这里，不知道什么原因

WAN口是动态IP
