LDAP Lightweight Directory Access Protocol is a simplified version of the standard
X.500 distributed directory model standard. LDAP specifies how a client
accesses a directory server. LDAP has emerged as a favored protocol since it
also handles key management with key and certificate storage.
Lifetime, Key Payload key lifetime defines the extent to which a single set of cryptographic
keys is used when applying VPN services to IP packets. Key lifetimes can be
defined by either the amount of data acted on by this single set of cryptographic
keys or the amount of time these keys are used before a key change. The more
often a key is changed, the “more secure” the system, although performance
may be affected by frequent key changes.

gateway If you are creating an extranet, choose “Not My security gateway” as the
Group’s associated security gateway. Doing this enables the “IP Address of
Extranet security gateway” entry field. Enter the IP address of the your partner
company’s security gateway. This is required if any VPNs serviced by a
VSU-1100, VSU-1010 or VSU-10 are in tunnel mode.
