Same here. RedHat 6.2, 2.2.17 kernel, FW1 4.1 SP2.

Per IP address. Should listen only on internal interface but IMHO there is
a bug, e.g. in output of 'fw lichosts' we can see a lot of external IPs
from external iface.

You can avoid those repeated messages by removing the file:
$FWDIR/database/fwd.h, then restarting VPN-1 & FireWall-1 and making
sure you do not violate the License Agreement again.

We've done exactly that and then we got "Failed to Load Security
Policy: No Valid FM License" error.
After reboot it counts ok, but fills up its internal-hosts-database with
previously seen/logged external IP addresses and then complains about the
number of internal hosts again.
