  IMPORTANT IPSEC NOTE: Starting with firmware 3.4+ the IPSec feature is included in the firmware.  A key is required to activate this option.  Please contact your distributor if you want to purchase this key or upgrade from an older IPSec purchase (before release 3.4).  Installing the firmware 3.7 will delete your existing IPSec software option from before firmware 3.4, you must request the new key from your distributor!
