border="0" src="images/new10.gif" width="28" height="12" alt="(New)">
<20></b><br>
</p>
<p>The Beta includes the following changes:<br>
</p>
<ol>
<li>An OLD_PING_HANDLING option has been added to shorewall.conf.
When set to Yes, Shorewall ping handling is as it has always been (see http://www.shorewall.net/ping.html).<br>
<br>
When OLD_PING_HANDLING=No, icmp echo (ping) is handled via rules and
policies just like any other connection request. The FORWARDPING=Yes option
in shorewall.conf and the 'noping' and 'filterping' options in /etc/shorewall/interfaces
will all generate an error.<br>
<br>
</li>
<li>It is now possible to direct Shorewall to create a "label"
such as<61> "eth0:0" for IP addresses that it creates under ADD_IP_ALIASES=Yes
and ADD_SNAT_ALIASES=Yes. This is done by specifying the label instead of
just the interface name:<br>
<20><br>
<20><> a) In the INTERFACE column of /etc/shorewall/masq<br>
<20><> b) In the INTERFACE column of /etc/shorewall/nat<br>
<20></li>
<li>When an interface name is entered in the SUBNET column of
the /etc/shorewall/masq file, Shorewall previously masqueraded traffic from
only the first subnet defined on that interface. It did not masquerade traffic
from:<br>
<20><br>
<20><> a) The subnets associated with other addresses on the interface.<br>
<20><> b) Subnets accessed through local routers.<br>
<20><br>
Beginning with Shorewall 1.3.14, if you enter an interface name in the
SUBNET column, shorewall will use the firewall's routing table to construct
the masquerading/SNAT rules.<br>
<20><br>
Example 1 -- This is how it works in 1.3.14.<br>
<20><> <br>
<pre><EFBFBD><EFBFBD> [root@gateway test]# cat /etc/shorewall/masq<br> #INTERFACE<43><45><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD> SUBNET<45><54><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD> ADDRESS<br> eth0<68><30><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD> eth2<68><32><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD> 206.124.146.176<br> #LAST LINE -- ADD YOUR ENTRIES ABOVE THIS LINE -- DO NOT REMOVE</pre>
<pre><EFBFBD> [root@gateway test]# ip route show dev eth2<br> 192.168.1.0/24<32> scope link<br> 192.168.10.0/24<32> proto kernel<65> scope link<6E> src 192.168.10.254<br></pre>
<pre><EFBFBD> [root@gateway test]# shorewall start<br> ...<br> Masqueraded Subnets and Hosts:<br> To 0.0.0.0/0 from 192.168.1.0/24 through eth0 using 206.124.146.176<br> To 0.0.0.0/0 from 192.168.10.0/24 through eth0 using 206.124.146.176<br> Processing /etc/shorewall/tos...<2E><br></pre>
When upgrading to Shorewall 1.3.14, if you have multiple local subnets
connected to an interface that is specified in the SUBNET column of an
/etc/shorewall/masq entry, your /etc/shorewall/masq file will need changing.
In most cases, you will simply be able to remove redundant entries. In some
cases though, you might want to change from using the interface name to
listing specific subnetworks if the change described above will cause masquerading
to occur on subnetworks that you don't wish to masquerade.<br>
<20><br>
Example 2 -- Suppose that your current config is as follows:<br>
<pre><EFBFBD><EFBFBD> [root@gateway test]# cat /etc/shorewall/masq<br> #INTERFACE<43><45><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD> SUBNET<45><54><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD> ADDRESS<br> eth0<68><30><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD> eth2<68><32><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD> 206.124.146.176<br> eth0<68><30><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD> 192.168.10.0/24<32><34><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD><EFBFBD> 206.124.146.176<br> #LAST LINE -- ADD YOUR ENTRIES ABOVE THIS LINE -- DO NOT REMOVE</pre>

<p><b>1/17/2003 - shorewall.net has MOVED</b><b></b></p>
<p>Thanks to the generosity of Alex Martin and <a
href="http://www.rettc.com">Rett Consulting</a>, www.shorewall.net and
ftp.shorewall.net are now hosted on a system in Bellevue, Washington. A
big thanks to Alex for making this happen.<br>
</p>
<p><b>1/13/2003 - Shorewall 1.3.13</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>

<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>

<p><b>12/7/2002 - Shorewall Support for Mandrake 9.0</b><b>
</b></p>
<p>Two months and 3 days after I pre-ordered Mandrake 9.0, it was finally
delivered. I have installed 9.0 on one of my systems and I am
now in a position to support Shorewall users who run Mandrake 9.0.</p>
<p><b>12/6/2002 - <20>Debian 1.3.11a Packages Available</b><br>

<p><b>12/3/2002 - Shorewall 1.3.11a</b><b>
</b></p>
<p>This is a bug-fix roll up which includes Roger Aich's fix for DNAT
with excluded subnets (e.g., "DNAT foo!bar ..."). Current 1.3.11
users who don't need rules of this type need not upgrade to 1.3.11.</p>

<p><b>11/24/2002 - Shorewall 1.3.11</b><b><EFBFBD></b><b>
</b></p>
<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-&gt;fw policies now generate
a startup error. fw-&gt;fw rules generate a warning and are
ignored</li>
</ul>
