Hi all,


I am new to Firewalling and the ASA products. I have a question regarding the ASA 5500 tunneling capacity. If I have an ASA 5500(at a remote site) with a tunnel established to an ISR (headquarters), what is the number of concurrent sessions allowed in this tunnel? Put in another way, what is the maximum number of computers behind the ASA 5500 that are allowed through the tunnel?


Any suggestions or information to help clarify this would be greatly appreciated.


Thanks,

SK

Thank you for the prompt response.


I would like some clarification on the difference between the:

- Max firewall connections

- Max site-to-site & remote access VPN sessions

- Max SSL VPN user sessions


Which one of these categories addresses my question? The max number of computers allowed throught the site-to-site tunnel?


Thanks again!

SK

Think of connections tcp/udp , not computers..


The overwall firewall maximun concurrent connections combining every other connections ssl, http.. etc..


Maximun site-to-site and RAs peer tunnels ( Not connections ) just peer tunnels , that inlcudes L2L tunnels and RA tunnels.


For SSL vpn users is the Maximung SSL concurrent SSL session the firewall is allow to handle.

So, the max concurrent tcp/udp connections that the ASA 5500 can handel is 10000/25000, correct?
