Installing and Configuring HP-UX IPFilter
Step 4: Adding Rules to the Rules Files
Chapter 1 9
NOTE IPFilter NAT functionality and the associated commands and utilities
are not suppored with IPv6.
Filtering rules added to /etc/opt/ipf/ipnat.conf are loaded when the
system is booted. If you do not want the rules to load on bootup, place
your rules in an alternate location, such as /etc/ipnat.conf. You can
then load these rules manually using the ipnat command.
To enable the NAT functionality, you must configure at least one filter
rule using the ipf command. If you do not want to use the filtering
functionality, you should configure a redundant rule. For example:
pass in all
See the example NAT ruleset in Appendix A, “HP-UX IPFilter
Configuration Examples,” on page 147 for assistance in putting your
NAT rules together. You can find additional information on NAT
functionality in “map and portmap: Basic NAT” on page 39 and “The
ipnat Utility” on page 101.
