One of my new assignments involve integrating PIX 515 & VPN concentrators in to a single ASA 5540. I researched the cisco site & docs for any limitations of ASA in terms of number of site-to-site VPN's, usergroups, user accounts, throughput, max-connections etc. I also referred the feature comparison sheet for various models, but looks like parameters given are the max supportd by device for any license.
I just wanted to know, what would be the limitations of ASA firewall version for the above mentioned parameters. Any tips from your experience are welcome.
