4.3.3 Carrier > Keepalive
The Keep alive tab allows for the configuration of the keep alive features of the IPn4G. The
IPn4G can either do a ICMP or HTTP keep alive by attempting to reach a specified address at a
regular interval. If the IPn4G cannot reach the intended destination, it will reset the unit in an
attempt to obtain a new connection to the carrier.
Enable or Disable the keep alive functions in the IPn4G.
