I am trying to figure out an issue I am having with AnyConnect 2.5. After I login to the SSL VPN Portal and download and install the client I receive this message. Also once the client installs I have no network connectivity at all. Once I uninstall the client I am able to access the Internet and network connectivity is restored. Its obviously a config issue but I cant figure out where I am going wrong. I am also unable to change the connect to field as its locked down.
This is occurring because you, in your profile config, have it configured for always on VPN connectivity. AC 2.5 and ASA 8.3 introduced the capability to enforce always-on connectivity for the purpose of providing greater control and security over endpoints. This can be corrected by either modifying your profile, or making an exception through DAP or ASA GP. I have posted a link to the doc below. Please refer to the sections under trusted network detection and always on VPN.
Hope this helps. Let me know if you have further questions.
