Hi all,
 
I'm running FW1 4.0 sp4 (build 4066) on NT.  I'm seeing the message "too many internal hosts" in my firewall log.  I've already setup the external interface to be listed in the external.if file and have also reviewed the information on www.phoneboy.com .  It would seem that we've finally surpassed our license limit (100).
 
I've looked in the Event Viewer on the firewall (NT box) and noticed that there are a huge neumber of errors from FW1 - each listing an IP address.  I'm assuming that each IP was one that was unfortunate enough to be "outside" that limit.
 
However, there are at least 2 IP addresses that are repeated more than a handful of times that are NOT from within my internal network nor are they any part of the Class C we use in our DMZs.  They have both been dropped by Rule 0 - I'm assuming anti-spoofing.  One of them is sending HTTP and has a destination address that isn't part of this network. 
 
1. Why are these addresses listed in the internal hosts file?  Is this possibly a bug in the FW?
 
2. How does the firewall determine which IP addresses to place into the hosts file?
 
TIA.
