Hi lftekhar,
Thk you for the url link.
Can i confirm if 2000 simultaneous vpn tunnels refer to capability of supporting 2000 simultaneous vpn connections to the firewall?

As per my understanding value 2000 means that 515E supports up to 2000 Security Associations, NOT individual tunnels.
Easch IPSEC tunnel has 3 SAs (IKE SA, Tx SA, Rx SA). Depending on how elaborate your access-lists are, these can
use additional SA's.
In summary there are approximately 5 to 7 SA's per tunnel in a typical
configuration.
With assumption of 7 SAs per tunnel.The total comes to 285 unique tunnels.
