@huihen 只记得是苏联知道美国要使用核武器后，立即参战占领东北。

貌似情况一样啊 。

@sandtears 路由表中的 Gateway 应该是正确的，因为写的条目少的时候，是正确的。

@cj1324 TP-link TL-WDR4310 http://wiki.openwrt.org/toh/tp-link/tl-wdr4310

都没有认真搜索和看懂硬件配置就做起来了。 ;*(

@LazyZhu 是，VPN 已经建立了，以上都是在 VPN 运行起来后的情况。

1.第一段是说 pptp 有问题？

2.没有错误的装上了。

3.vpn 信息涂抹过。


有什么办法可以测试安装的 vpn 是否正确呢？

@ericFork 不好意思，这两个 log 我找了一下没有找到，是在什么位置？

关闭 Linux ，重启路由器还是不行。 :(

ppp-mod-pptp 装上了 ！


最后发现，是 opkg 的配置文件（/etc/opkg.conf 中第一行）与下载系统文件的路径不符合，修改后，可以正确安装了。

自己后来确实修改过 /etc/opkg.conf ，但最初并没有动，原因先不找了。

再次感谢各位 :)

@letitbesqzr 我下载到了 ppp-mod-pptp_2.4.5-10_ar71xx.ipk ，但不知道怎么在 Linux 下面安装？

重装了 OpenWrt ，版本是 12.9 。

但是执行 opkg install ppp-mod-pptp 还是失败

显示：

root@OpenWrt:/# opkg install ppp-mod-pptp
Unknown package 'ppp-mod-pptp'.
Collected errors:
* opkg_install_cmd: Cannot install package ppp-mod-pptp.
root@OpenWrt:/#

不知道为什么。

哦，看见方法了，我真弱。 :(
