HP-UX IPFilter Version 17 Administrator's Guide

4 Configuring and Loading IPv6 Filter Rules
This chapter describes how to configure and manage IPv6 filter rules.
It contains the following sections:
• “IPv6 Filter Rules Configuration File” (page 45)
• “Features Not Supported with IPv6” (page 46)
• “IPv6 Filter Rule Syntax Differences” (page 46)
• “Loading IPv6 Filter Rules” (page 49)
4.1 IPv6 Filter Rules Configuration File
HP-UX IPFilter maintains IPv4 and IPv6 rules as separate rule sets. You cannot not configure
IPv6 filter rules in the same file with IPv4 filter rules, and you must administer IPv4 and IPv6
rule sets separately. The rule set (IPv4 or IPv6) for a rule is determined by the command-line
options and file used to load the rule. These options are described in “Loading IPv6 Filter Rules”
(page 49).
The default name for the HP-UX IPFilter IPv6 filter rules file is /etc/opt/ipf/ipf6.conf.
To specify an alternate IPv6 filter rules file name, set the IPF6_CONF parameter in the IPFilter
startup file, /etc/rc.config.d/ipfconf.
Any given rule will apply to either IPv4 or IPv6 according to the file and command options used
to load the rule, but will not apply to both IPv4 and IPv6. This includes rules with wildcard
addresses.
