9.4.3.4. Using Config Mode
IKE Configuration Mode (Config Mode) is an extension to IKE that allows NetDefendOS to
provide LAN configuration information to remote VPN clients. It is used to dynamically configure
IPsec clients with IP addresses and corresponding netmasks, and to exchange other types of
information associated with DHCP. The IP address provided to a client can be either be based on a
range of predefined static IP addresses defined for Config Mode or it can come from DHCP servers
associated with an IP Pool object.
An IP pool is a cache of IP addresses collected from DHCP servers and leases on these addresses are
automatically renewed when the lease time is about to expire. IP Pools also manage additional
information such as DNS and WINS/NBNS, just as an ordinary DHCP server would. (For detailed
information on pools see Section 5.5, “IP Pools”.)
