There is no extra hardware module on this router, and i want to know the number>
What i've found on internet, is that is support up to 10 Cisco VPN Clients, but i've already tested it with 14 simultanious users, so i'm in doubt.

Hi,Nowadays I have a customer

Hi,

Nowadays I have a customer with a Cisco 2821 for Internet connectivity and VPN Service with 200 VPN clients with factory RAM and Flash memory, if you check documentation this router can support up to 1500 VPN tunnels with AIM-EPII-Plus Module.

http://www.cisco.com/c/en/us/products/routers/2821-integrated-services-router-isr/index.html

You can use the CIsco 2821 with Easy VPN Server on Headquarters and Branch router with Easy VPN Remote.

I recommend you upgrade the IOS version to c2800nm-adventerprisek9-mz.124-20.T.bin

If it was useful please rate.

Please Note: The Maximum Tunnel Scalability test is done with no data passing over the tunnels to only determine maximum number. So again it depends upon the factor that untill there is no problem with Bandwidth, CPU and Memory.
