HP-UX IPFilter V17.05 Release Notes for 11i v2

4 Known Issues and Workarounds
• The startup script for HP-UX IPFilter automatically disables the
ip_forward_directed_broadcasts parameter. This keeps the system from being
subjected to broadcast-storm attacks that can bring down a network.
• If rules are configured using stdin, rules numbers are not assigned properly to individual rules.
Sample output displaying the problem:
