Offer embedded client mode to connect to DynDNS.org like Netgear and Linksys do. A lot of us support 5 user home models that don't want to pay for SMP. Id a 30 dollar NAT router can do it, Sofaware/Checkpoint can as well.
A lot of us know about the built in dynamic DNS but also some of us have a DDNS address wed like to already use with the router, or administer as part of a DDNS group... Its nice to know that theres a myzonealarm address but having a friendly name DDNS (from say dyndns.org) in addition to the built in one has its uses.
We are already using a dyndns.org for quite some years before we purchased a checkpoint device. We have to use a software dyndns updater to carry on using the hostname.
It is only current downside I see to the checkpoint device. (There were 2 before until firmware v8.0 which introduced the antispam scanning)
