HP-UX IPFilter Version A.03.05.14 Administrator's Guide

HP-UX and IPv6 Support
Using IPv6 Support in HP-UX IPFilter
Chapter 6112
Key Points to Note
•If the -6 option is not specified in the ipf and ipfstat commands,
the operation is applied to IPv4 rules.
IPv6 filtering is enabled only if IPv6 interfaces are configured.
The following separate files for IPv4 and IPv6 are loaded during
boot:
—IPv4: opt/ipf/ipf.conf
—IPv6: opt/ipf/ipf6.conf
Rules can be loaded from any other file, but IPv4 and IPv6 rules
should not be loaded from the same file.
