dd-wrt同时作为vpn服务器和客户端时autoddvpn无效 #52

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago
我的使用场景是dd-wrt路由器同时作为pptp的客户端和服务器端�
��一般情况下,路由器是客户端连接到国外的一个pptp服务器��
�这时能正常的分发国内国外路由,但是一旦有用户通过pptp连
接到路由器时,路由表将会发生改变,default 
gw会再次变成wan_ip,然后autoddvpn就没有效果了,无法突破封锁
。

route最后一行的情况
无vpn用户连接路由器时:
default         172.16.36.1     0.0.0.0         UG    0      0        0 ppp1
有vpn用户连接路由器后:
default         1.64.70.125.bro 0.0.0.0         UG    0      0        0 ppp0

请问有没有什么方法,可以使autoddvpn没有影响?

路由器型號:TP-Link wr741n
DD-WRT版本:DD-WRT v24-sp2 (12/24/10) std

感謝你的回報,我的開發環境並沒有讓DDWRT同時兼做PPTP 
server, 所以這個部分我還沒碰過。

也許你試試看用graceMode的機制,在graceMode default gw是wan gw, 
所以應該不存在default gw跑掉的問題。

我的环境是路由器跑gracemode,做PPTP服务端,做OPENVPN客户端。
目前只有一个问题,我的nexus 
s通过PPTP拨入后,只要不运行youtube或者twitter之类的app。就能�
��浏览器正常打开twitter,youtube的网站(当然也包括其它网站�
��。如果打开了这些app,android的网络就完全断掉,连PPTP隧道�
��立的网关都ping不通(机器没有root,没办法执行其他命令排�
��);
还试过以下两种方式
1、手机开启wifi热点功能,笔记本接入后拨PPTP回路由器。一��
�正常
2、手机开启wifi热点功能,并拨PPTP回路由器。手机能正常翻��
�,笔记本接入wifi热点后连手机IP都ping不通。

由于我的路由器没有jffs分区,只能采用wget方式,所以不能测
试。不过我觉得gracemode应该可行,它没有更改defualt gw。

是的,請試試看graceMode

不知道對於沒有JFFS的ddwrt
有沒有辦法是用GraceMode。。

我在用的就是DD 
OPENVPN版本。沒有jffs。只能用pptp的方式。。。:(((

如果想用classicMode,可以试试我改好的脚本。见附件。

我也遇到了一模一样的问题:我的dd-wrt路由器兼做pptp 
server和client。路由器作为client连接到国外的服务器,一切运��
�正常。但是当有pptp客户端连接到路由器的server之后,default 
gw就变成了wan_gateway了。

我在ssh执行如下命令:
route del default gw $OLDGW
route add default gw $VPNGW
效果就恢复了。

所以初步估计是客户端拨进pptp sever的时候,更改了default gw。

排查了一下,看到:/tmp/pptpd/ip-up里面有一句:startservice 
set_routes -f
不是很清楚它的作用。

请指教。

补充说明一下,我用的是wget模式,从局域网的ftp服务器取回�
