The easiest way that I know of is to insert your calls to iptables into the /etc/rc.d/rc.local script. (Or, really, any startup script . . . rc.local is just good since it is for local configuration options.

Are you asking in what directory the iptables command can be found?

kakaka after restart I think customisations which wrote in console are deleted

I don't know about Slackware, but on Fedora the iptables file is located at /etc/sysconfig/iptables.

You can always try:

Code:

# find /etc -name "iptables"

Usually it is located at /usr/sbin/iptables

Be sure to invoke it with its absolute path for each rule that you add.

And there is a difference?

The cfdg file is probably under /etc

Code:

find /etc -name '*iptables*' -print 2>/dev/null

note the single quotes to ensure that only 'find' sees the wildcards, not the shell.
If not found, try searching the entire drive space ie

Code:

find / -name '*iptables*' -print 2>/dev/null

as root user in both cases.

This is from /etc/rc.d/rc.inet2:

Code:

...
# If there is a firewall script, run it before enabling packet forwarding.
# See the HOWTOs on http://www.netfilter.org/ for documentation on
# setting up a firewall or NAT on Linux.  In some cases this might need to
# be moved past the section below dealing with IP packet forwarding.
if [ -x /etc/rc.d/rc.firewall ]; then
  /etc/rc.d/rc.firewall start
fi

So, as you can see, the firewall rules in Slackware go in rc.firewall.
