Hello,
>> 1. I want to know if we will still be able to use the existing VPN client (v4) to connect or if that will have to be completely replaced by Anyconnect?
SSL VPN and IPsec VPN can co-exist in the same configuration, but AnyConnect is a separate client from the traditional IPsec VPN client and is compatible with 64-bit systems (as is the new 5.0.7 beta IPsec client).
>> 2. Is Anyconnect client software or is it a web-based connection? (i.e; user navigates to IP or vpn.domain.com and can login) If it is web-based... what determines the login?
AnyConnect is a software client that can be pushed to the workstation by the net device or installed manually. You can login one of two ways: by navigating the to IP address of the net device and logging through the web portal, or by connecting via the installed client software. The user credentials can be obtained through different means, ie. local auth, LDAP, TACACS, etc. The group policy of individual user attributed determine which users are capable of using SSL VPN and/or IPsec VPN.
My only experience with configuring AnyConnect is with ASA hardware and is limited. Someone with more experience might chime in with other info.
Hope this helps!
James
