We're setting up an AnyConnect VPN on our Firepower 1140. When setting it up on either the ASDM or the CLI, it requires a client image. What is this asking for exactly? All the examples I see are older, with things like anyconnect-win-2.3.0254-k9.pkg. Is this the same as the client the end user would use or is it some special image that is used only on the firewall?
However, if I go to software.cisco.com and find the AnyConnect downloads section, it's just a bunch of files of different types, like 'predeploy' or 'webdeploy'. Is this a newer thing, where it is either one or the other? So if we wanted to do predeploy we'd have to upload the .pkg for that? I also have problems downloading because its asking for entitlement but that is a different question, and its probable my company HQ has the access I need.
Anyway, I have a 'anyconnect-win-4.2.01022-k9.pkg' image loaded on the ASA currently. But the users all have a later version of the client software on their laptops, since they install it using the file 'anyconnect-Windows-4.7.00136-core-vpn-predeploy-k9.msi' (they currently connect to a node in Asia but that is slow so I'm trying to set up one here at the office the US). Would this mismatch cause problems, or is that okay?
