设置autoddvpn后域名无法解析

[GoogleCodeExporter]

請描述一下您進行怎樣的操作之後碰到了問題
1.在dd-wrt中设置了autoddvpn，然后重启
2.登录dd-wrt中ping任何网址，均返回 bad address
3.局域网中某些客户端自动获取ip后，dns为路由器，这种情况�
��，任何域名都无法解析

你期待是怎樣的結果，然而卻出現了什麼情形？
被墙网站走VPN，否则直接访问，但是dd-wrt中dns解析有问题

請提供以下資訊：

1. 您的路由器型號：buffalo g300nh
2. DD-WRT版本：DD-WRT v24-sp2 (05/08/11) std (SVN revision 16994)
3. 您的作業系統：WIN7 Ultimate 32bit
4. 您的瀏覽器版本：IE9
5. autoddvpn的連線模式(pptp+wget, pptp+jffs, openvpn+jffs等)：pptp+jffs
6. autoddvpn的運行模式，傳統模式(classicMode)還是優雅模式(g
raceMode)：graceMode
7. DD-WRT WAN口連線模式是 pptp or dhcp or static ：pppoe
8. 運行autoddvpn之後DD-WRT 的命令輸出 # route -n  | tail -n 20 ：
root@DD-WRT:~# route -n  | tail -n 20

注意一下dnsmasq 
options需要適當的折行，格式不能出問題，否則dnsmasq會無法正
確運作，從這裡檢查看看，必要的話清空dnsmasq 
options測試看看。

重排了一下dnsmasq果然就正常了
多谢
但是还有一个问题就是vpn掉了不会自动重连

你是用pptp vpn的，vpn掉了的話ppp1 
這個device會消失，如果沒有消失表示DDWRT不認為是掉了，很可
能只是掉包或網路不穩，但已經無法使用。

這只能選擇線路穩定的pptp 
vpn來解決了，或者用openvpn也會有ping-restart之類的機制可以強�
��重連。

目前autoddvpn使用了openvpn的ping-restart这种重连机制吗？
在现在的网络环境下，线路稳定的vpn不好找啊

Original comment by sha...@gmail.com on 12 May 2011 at 5:25

[GoogleCodeExporter]

openvpn設置可以自己定義 ping-restart
看這份文件

好，先去找找支持openvpn的vpn
顺便请教一下，如果vpn掉了，怎么手动重连？

Original comment by sha...@gmail.com on 13 May 2011 at 10:39

[GoogleCodeExporter]

詳細命令我不大記得了
可能是 stopservice|startservice pptp 或pptpclient
