I have a 1841 router setup with SSL vpn using the anyconnect client. Before upgrading to anyconnect 2.5 I had 2.3 installed and the start before logon feature worked for XP hosts but not for Windows 7. So I upgraded. Now when trying to do start before logon I get "Network Access: Blocked - Web Authentication Required". From what I have read this is for captive portal detection. The internet connection I am testing on does not have a captive portal. I have looked through the anyconnect 2.5 configuration guide, the release notes and the IOS 15.1 guides and can't find anything. Any help would be appreciated.

User Auth is being done via SecureACS and it is also assigning an ACL to the session that is configured on the router.
