Works with 11.2 with caveat – Cisco Secure Client Review

With the server side workaround, AnyConnect now works on iOS 11.2, so I'm revising my rating from 1 to 5 stars. Previous review: The VPN client will fail to establish a connection if running on a device with cellular and Wi-Fi both enabled. I reported this bug months ago but nobody has fixed it yet. Workaround is to disable cellular then you will be able to establish a VPN connection over Wi-Fi. If you want to establish a VPN connection over cellular, you will need to disable Wi-Fi.
