I would think it to be a good idea for Astaro to generate a Cisco VPN profile (.pcf) for import into the Cisco VPN client, that can be downloaded from the user profile. Just like Astaro does for an OpenVPN profile with the SSL VPN. Much easier to explain to an end user how to add a PCF file than have them manually enter in the host name, IP, etc.
Edit: FYI to an dev who may bother to read this, the pcf file is a plain text file, so should be a simple thing to do. [:)]
