我在 Windows 8 笔记本电脑上通过 Cisco AnyConnect 3.1.04072 设置了 VPN。我可以连接到 VPN,但一旦连接到 VPN,所有互联网流量就会停止。我已经研究了好几天,但还没有找到解决办法。我发现的一些建议包括在属性中取消选中“在远程网络上使用默认网关”,更新驱动程序,以及在注册表中编辑一个键。
我们有三台使用 AnyConnect 的机器(一台 Mac、一台 Win7 和我的 Win8),它们使用相同的 vpn 服务,只有我的机器有这个问题。而且,这个问题是几天前思科发布 3.1.04072 更新时才开始的。
配置如下...

对 DNS 服务器 172.16.1.200 执行 ping 操作失败。我尝试在控制面板属性中将 DNS 服务器更改为其他服务器,例如 google 的 DNS,但结果是一样的。所有 ping 操作都失败,tracert 和 nslookup 也失败:
>nslookup
DNS request timed out.
timeout was 2 seconds.
Default Server: UnKnown
Address: 172.16.1.200
如果有人能给我指明正确的方向我将不胜感激!

在“网络和共享中心”中的“本地连接”下禁用 Microsoft PC 上的 IPv6,然后回复我。此方法在我们三台使用不同操作系统的计算机上均有效。

答案3
您无法上网的原因是 ASA 设置为全隧道模式,这意味着您的所有流量都将通过 VPN 隧道。如果您可以访问 ASA,请将其设置为拆分隧道模式,然后您就可以再次访问互联网。
