I found the same page and intend to try that approach. Will report back after testing.

Something like the following should do the trick:
Code:
ipf -IFa && ipf -If /etc/ipf/ipf.conf && ipf -s -y

Taken from http://serverfault.com/questions/638739/refresh-ipfilter-configuration-while-keeping-state , but forum doesn't let me post clickable urls yet.


RBATTE1 adding link:- solaris - Refresh ipfilter configuration while keeping state - Server Fault
This worked perfectly. We tested it carefully.

NAME
ipfilter - IP packet filtering software IP Filter is software that provides packet filtering capabilities. On a properly setup system, it can be used to build a firewall. The IP Filter feature requires that the file /etc/ipf/pfil.ap be modified to include the names of the network interface(s) to be filtered. A system with filtering on the hme and qfe interfaces would have entries in /etc/ipf/pfil.ap such as those shown below. # IP Filter pfil autopush setup # # See autopush(1M) manpage for more information. # # Format of the entries in this file is: # #major minor lastminor modules #le -1 0 pfil #qe -1 0 pfil hme -1 0 pfil qfe -1 0 pfil See for more information. See attributes(5) for a description of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Evolving | +-----------------------------+-----------------------------+ ipf(1M), ipnat(1M), ipf(4), ipnat(4), attributes(5) To view license terms, attribution, and copyright for IP Filter, the default path is /usr/lib/ipf/IPFILTER.LICENCE. If the Solaris operat- ing system has been installed anywhere other than the default, modify the given path to access the file at the installed location. In the current release of the Solaris operating system, IP Filter startup configuration files are stored in /etc/ipf. 17 Feb 2005 ipfilter(5)
