i have to make design for one head quater and 400 locations. I was thinking to install ASA 5520 in the HQ and use Cisco 851 routers on each remote location. Then make IPsec tunnels to each remote location. I have experince in making tunnels and with all his equipment. My queston is, can ASA 5520 handle all this locations, bandwidth wont be more then 20MB/s?
Best regards Nemanja
