In ASDM I am try to set Maximum Number of SSL Sessions. According to Cisco documentation my Cisco ASA 5510 should be able to support 250 simultaneous SSL VPN sessions. But if you check my screen shot you will see that my ASA will not permit more than 1 or 2! What is up with that??
What am I missing? I am running ADSM 6.2 and the image is 8.21.
ASA comes with 2 free licences. To use more that 2 you will need to buy licences. The 250 is the maximum number the box will support.
All ASA models (including the 5510), comes from factory supporting only 2 SSL VPN connections.
Indeed, the ASA can support up to 250 SSL VPN connections, but for that, you must purchase an additional license.
