ISAKMP phase 2
Encryption mode: Select the VPN ISAKMP phase 2 encryption mode.
Authentication mode: Select the VPN ISAKMP phase 2 authentication mode.
Diffie-Hellman group: Select the VPN ISAKMP phase 2 DH group. Increasing the DH Group number increases
the level of encryption implemented for PFS.
SA life time (default = 28800): Enter the number of seconds for the VPN ISAKMP phase 2 Lifetime, which
is the period of time that passes before establishing a new IPSec security association (SA) with the remote
endpoint.
Advanced Settings
Anti-replay: Anti-replay is the method of not allowing an intercepted packet message to be sent to the
recipient multiple times without the original sender knowing (default = Disable).
Dead Peer Detection (DPD): Enable or disable the Dead Peer Detection. DPD is a method of detecting a dead
Internet Key Exchange (IKE) peer. It sends a DPD packet to the peer every 60 seconds with no traffic and
attempts to connect normally. If the DPD packet fails 5 times the VPN will continuously re-establish a
connection (default = Disable).

Cellular Reconnection
Carriers disconnect idle mobile device connections in order to save bandwidth for other on-line users and
applications. To keep the ioLogik W5300 Always On, the ioLogik W5340 must not only have the capability to
detect the cellular connection and reconnect to the network once it is disconnected, but also needs to send out
signals (ICMP package) to notify carriers that the ioLogik W5340 is still alive.
