Cisco的VPN客户端最近报“AnyConnect was not able to establish connection to the specified secure gateway.“ 导致连不上公司VPN了。
有人说取消共享
Problem: AnyConnect was not able to establish a connection to the specified secure gateway. Please try connecting again.
Environment: Windows 7; Cisco AnyConnect Secure Mobility Client; VPN Connection
Solution: Uncheck the network sharing option.
但是搞不定啊，我本来就没开共享。。。
还是Cisco官方的解答给力

运行 ”services.msc“
把图中的Internet Connection Sharing禁用就行了
