one of my client just installed window 8 and he is not able to connect with anyconnect anymore. if he connect with ASA for anyconnect version 2019 it work fine. but i have tried all different version on router. but when user try to connect with router for anyconnect then there is gateway error. it ask for connect anyway then it stop. connection failed. i tried 00605.. anyconnect on router but still no luck. i think, i have to make some changes. but dont know what changes on router. window 7 has no issue.
