|

</b><br>
|
||
</p>
|
||
|
||
<p>Just includes a few things that I had on the burner:<br>
|
||
</p>
|
||
|
||
<ol>
|
||
<li>A new 'DNAT-' action has been added for entries in the /etc/shorewall/rules
|
||
file. DNAT- is intended for advanced users who wish to minimize the number
|
||
of rules that connection requests must traverse.<br>
|
||
<br>
|
||
A Shorewall DNAT rule actually generates two iptables rules: a header rewriting
|
||
rule in the 'nat' table and an ACCEPT rule in the 'filter' table. A DNAT-
|
||
rule only generates the first of these rules. This is handy when you have
|
||
several DNAT rules that would generate the same ACCEPT rule.<br>
|
||
<br>
|
||
<20><> Here are three rules from my previous rules file:<br>
|
||
<br>
|
||
<20><><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD> DNAT<41><54> net<65> dmz:206.124.146.177 tcp smtp - 206.124.146.178<br>
|
||
<20><><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD> DNAT<41><54> net<65> dmz:206.124.146.177 tcp smtp - 206.124.146.179<br>
|
||
<20><><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD> ACCEPT net<65> dmz:206.124.146.177 tcp www,smtp,ftp,...<br>
|
||
<br>
|
||
<20><> These three rules ended up generating _three_ copies of<br>
|
||
<br>
|
||
<20><><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD> ACCEPT net<65> dmz:206.124.146.177 tcp smtp<br>
|
||
<br>
|
||
<20><> By writing the rules this way, I end up with only one copy of the ACCEPT
|
||
rule.<br>
|
||
<br>
|
||
<20><><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD> DNAT-<2D> net<65> dmz:206.124.146.177 tcp smtp -<2D> 206.124.146.178<br>
|
||
<20><><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD> DNAT-<2D> net<65> dmz:206.124.146.177 tcp smtp -<2D> 206.124.146.179<br>

<20><><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD> ACCEPT net<65> dmz:206.124.146.177 tcp www,smtp,ftp,....<br>
|
||
<br>
|
||
</li>
|
||
<li>The 'shorewall check' command now prints out the applicable policy
|
||
between each pair of zones.<br>
|
||
<br>
|
||
</li>
|
||
<li>A new CLEAR_TC option has been added to shorewall.conf. If this
|
||
option is set to 'No' then Shorewall won't clear the current traffic control
|
||
rules during [re]start. This setting is intended for use by people that prefer
|
||
to configure traffic shaping when the network interfaces come up rather than
|
||
when the firewall is started. If that is what you want to do, set TC_ENABLED=Yes
|
||
and CLEAR_TC=No and do not supply an /etc/shorewall/tcstart file. That way,
|
||
your traffic shaping rules can still use the 'fwmark' classifier based on
|
||
packet marking defined in /etc/shorewall/tcrules.<br>
|
||
<br>
|
||
</li>
|
||
<li>A new SHARED_DIR variable has been added that allows distribution
|
||
packagers to easily move the shared directory (default /usr/lib/shorewall).
|
||
Users should never have a need to change the value of this shorewall.conf
|
||
setting.<br>
|
||
</li>

<p><b>12/27/2002 - Shorewall 1.3.12 Released</b><b>
|
||
</b></p>
|
||
|
||
<p> Features include:<br>
|
||
</p>
|
||
|
||
<ol>
|
||
<li>"shorewall refresh" now reloads the traffic shaping rules
|
||
(tcrules and tcstart).</li>
|
||
<li>"shorewall debug [re]start" now turns off debugging after
|
||
an error occurs. This places the point of the failure near the end of
|
||
the trace rather than up in the middle of it.</li>
|
||
<li>"shorewall [re]start" has been speeded up by more than
|
||
40% with my configuration. Your milage may vary.</li>
|
||
<li>A "shorewall show classifiers" command has been added
|
||
which shows the current packet classification filters. The output from
|
||
this command is also added as a separate page in "shorewall monitor"</li>
|
||
<li>ULOG (must be all caps) is now accepted as a valid syslog
|
||
level and causes the subject packets to be logged using the ULOG target
|
||
rather than the LOG target. This allows you to run ulogd (available from
|
||
<a href="http://www.gnumonks.org/projects/ulogd">http://www.gnumonks.org/projects/ulogd</a>)
|
||
and log all Shorewall messages <a href="shorewall_logging.html">to a
|
||
separate log file</a>.</li>
|
||
<li>If you are running a kernel that has a FORWARD chain
|
||
in the mangle table ("shorewall show mangle" will show you the chains
|
||
in the mangle table), you can set MARK_IN_FORWARD_CHAIN=Yes in <a
|
||
href="Documentation.htm#Conf">shorewall.conf</a>. This allows for marking
|
||
input packets based on their destination even when you are using Masquerading
|
||
or SNAT.</li>
|
||
<li>I have cluttered up the /etc/shorewall directory with
|
||
empty 'init', 'start', 'stop' and 'stopped' files. If you already have
|
||
a file with one of these names, don't worry -- the upgrade process won't
|
||
overwrite your file.</li>
|
||
<li>I have added a new RFC1918_LOG_LEVEL variable to <a
|
||
href="Documentation.htm#Conf">shorewall.conf</a>. This variable specifies
|
||
the syslog level at which packets are logged as a result of entries in
|
||
the /etc/shorewall/rfc1918 file. Previously, these packets were always
|
||
logged at the 'info' level.<br>
|
||
</li>

</ol>
|
||
|
||
<p><b>12/20/2002 - Shorewall 1.3.12 Beta 3</b><br>
|
||
</p>
|
||
This version corrects a problem with Blacklist logging. In Beta
|
||
2, if BLACKLIST_LOG_LEVEL was set to anything but ULOG, the firewall would
|
||
fail to start and "shorewall refresh" would also fail.<br>

|
||
|
||
<p>In this version:</p>
|
||
|
||
|
||
|
||
<ul>
|
||
<li>A 'tcpflags' option has been added to
|
||
entries in <a href="Documentation.htm#Interfaces">/etc/shorewall/interfaces</a>.
|
||
This option causes Shorewall to make a set of sanity check on TCP packet
|
||
header flags.</li>
|
||
<li>It is now allowed to use 'all' in the
|
||
SOURCE or DEST column in a <a href="Documentation.htm#Rules">rule</a>.
|
||
When used, 'all' must appear by itself (in may not be qualified) and
|
||
it does not enable intra-zone traffic. For example, the rule <br>
|
||
<br>
|
||
<20> <20> ACCEPT loc all tcp 80<br>
|
||
<br>
|
||
does not enable http traffic from 'loc' to 'loc'.</li>
|
||
<li>Shorewall's use of the 'echo' command
|
||
is now compatible with bash clones such as ash and dash.</li>
|
||
<li>fw->fw policies now generate a startup
|
||
error. fw->fw rules generate a warning and are ignored</li>
