不好意思。。又是我。。不过这次换了路由器是H618B
請描述一下您進行怎樣的操作之後碰到了問題
1.按照HOWTO配好之后不能翻

你期待是怎樣的結果，然而卻出現了什麼情形？
期待能正常自动翻，结果不能翻，并且由于没有到国外的路��
�变成自动撞墙猫了。。。呵呵

請提供以下資訊：

1. 您的路由器型號：H618B
2. DD-WRT版本：DD-WRT v24-sp2 (06/03/10) mega
(SVN revision 14537)
3. 您的作業系統：WINDOWS
4. 您的瀏覽器版本：FF 3
5. autoddvpn的運行模式(pptp+wget, pptp+jffs, openvpn+jffs等)：pptp+jffs
6. DD-WRT WAN口連線模式是 pptp or dhcp or static ：dhcp
7. 運行autoddvpn之後DD-WRT 的命令輸出 # route -n  | tail -n 20 ：
59.192.0.0      192.168.0.1     255.192.0.0     UG    0      0        0 vlan1

(注意啊...没有default...)

如果方便的話，請參考這裡的說明，貼上autoddvpn.log內容

最後如果可能的話，請附上截屏或任何可能有幫助的夾檔
需要说明的是，确实开机PPTP自动拨上去了(log里可以看到,并��
�ifconfig里也确实有）..但是貌似就是在vpnup.sh 
ended的时候它自己就断了..而且default 
route也没有..所有非国内的网站都不能访问了...

一点补充
PPTP应该是比较稳定的...不启动autoddvpn的话可以看到

至少不会连上就断

vpnup 
pptp的时候确实在路由表里添加过正确的设置，但是紧接着VPN�
��断了
这个VPN服务器和上次G300NH配的是同一个VPN，目前G300NH比较稳��
�应该不是VPN服务器的问题

所以你的意思是同樣的VPN服務器同樣的autoddvpn設置，在G300NH��
�問題，在H618B會斷線是吧？

GoogleCodeExporter commented 9 years ago 
問一下，你的PPTP 
server的設置，是用hostname還是用IP？必須使用IP哦！

我更新了vpnup.sh, 做了一更多的logging方便debug, 
你更新一下vpnup.sh之後再試一次，然後把/tmp/autoddvpn.log貼上來
看看。

对,G300NH没问题,H618B短线,不过我用的是hostname不是IP,回家改成I
P的试试,多谢!!

OK那就是需要設定成IP的問題了，之後我想辦法做這部分的檢�
��並且在log提供warning。
