* an explanation of the rule specifications that we use
* sample commands that can be seen in the labs to relate to this document
* The lines that follow are similar as found in the iptables man pages.
** the items listed with [ ] square brackets are optional in the command
<pre> #iptables command chain rule-spec([match,] target/jump )
# service iptables save (Saves the current configuration
into /etc/sysconfig/iptables )
</pre>
== Options for Elements in the Structure ==
Considering the commands, chains, matches and targets/jumps... there are only a few of those that we will actually use, at least for this course. Matches can get a bit more complex and will be discussed next, but the others will be listed here.
The items that are listed in ( ) round brackets are there for informational purposes as we don't use them in our course for our configurations.
