<h3>1.4.8</h3>
|

<ul>
|
||||
<li>When a DNAT rules specifies SNAT (e.g., when <original dest
|
||||
addr>:<SNAT addr> is given in the ORIGINAL DEST column), the
|
||||
SNAT specification is effectively ignored in some cases.</li>
|

</ul>
|

This problem has been corrected in this <a

href="http://shorewall.net/pub/shorewall/errata/1.4.8/firewall">firewall
|
||||
script</a> which may be installed in /usr/share/shorewall/firewall as
|
||||
described above.<br>
|
||||
<h3>1.4.7</h3>
|
||||
<ul>
|
||||
<li>Using some versions of 'ash' (such as from RH8) as the
|
||||
SHOREWALL_SHELL causes "shorewall [re]start" to fail with:<br>
|
||||
<br>
|
||||

|
||||

Try `iptables -h' or 'iptables --help' for more
|

information.</li>
|
||||
<li>When more than one ICMP type is listed in a rule and your kernel
|
||||
includes multiport match support, the firewall fails to
|
||||
start. </li>
|
||||
<li>Regardless of the setting of LOGUNCLEAN, the value
|
||||
LOGUNCLEAN=info was used.</li>
|
||||
<li>After the following error message, Shorewall was left in an
|
||||
inconsistent state:<br>
|

Error: Unable to determine the routes through interface xxx<br>

</li>
|

|

</ul>
|

These problems have been corrected in this <a

href="http://shorewall.net/pub/shorewall/errata/1.4.7/firewall">firewall
|
||||
script</a> which may be installed in /usr/share/shorewall/firewall as
|
||||
described above.<br>
|
||||
<h3>1.4.6</h3>
|
||||
<ul>
|
||||
<li>If TC_ENABLED is set to yes in shorewall.conf then Shorewall
|
||||
would fail to start with the error "ERROR: Traffic Control
|
||||
requires
|
||||
Mangle"; that problem has been corrected in <a
|
||||
href="http://shorewall.net/pub/shorewall/errata/1.4.6/firewall">this
|
||||
firewall script</a> which may be installed in
|
||||
/use/share/shorewall/firewall as described above. This problem is also
|
||||
corrected in bugfix release 1.4.6a.</li>
|
||||
<li>This problem occurs in all versions supporting traffic control.
|
||||
If a MAC address is used in the SOURCE column, an error occurs as
|
||||
follows:<br>
|
||||
<br>
|
||||
<font size="3"><tt>iptables v1.2.8: Bad mac adress
|
||||
`00:08:B5:35:52:E7-d`</tt></font><br>
|
||||
<br>
|
||||
For Shorewall 1.4.6 and 1.4.6a users, this problem has been corrected
|
||||
in <a href="http://shorewall.net/pub/shorewall/errata/1.4.6/firewall">this
|
||||
firewall script</a> which may be installed in
|
||||
/usr/share/shorewall/firewall as described above. For all other
|
||||
versions, you will have to edit your 'firewall' script (in versions
|
||||
1.4.*, it is located in /usr/share/shorewall/firewall). Locate the
|
||||
function add_tcrule_() and in that function, replace this line:<br>
|
||||
<br>
|
||||
<span style="font-family: monospace;">r=`mac_match
|
||||
$source` </span><br>
|
||||
<br>
|
||||
with<br>
|
||||
<br>
|
||||
<span style="font-family: monospace;">r="`mac_match
|
||||
$source` "</span><br>
|
||||
<br>
|
||||
Note that there must be a space before the ending quote!<br>
|
||||
</li>
|
||||
</ul>
|
||||
<h3>1.4.4b</h3>
|
||||
<ul>
|
||||
<li>Shorewall is ignoring records in /etc/shorewall/routestopped that
|
||||
have an empty second column (HOSTS). This problem may be corrected by
|
||||
installing <a
|
||||
href="ftp://ftp1.shorewall.net/pub/shorewall/errata/1.4.4b/firewall"
|
||||
target="_top">this firewall script</a> in
|
||||
/usr/share/shorewall/firewall
|
||||
as described above.</li>
|
||||
<li>The INCLUDE directive doesn't work when placed in the
|
||||
/etc/shorewall/zones file. This problem may be corrected by installing <a
|
||||
href="ftp://ftp1.shorewall.net/pub/shorewall/errata/1.4.4b/functions"
|
||||
target="_top">this functions script</a> in
|
||||
/usr/share/shorewall/functions.<br>
|
||||
</li>
|
||||
</ul>
|
||||
<h3>1.4.4-1.4.4a</h3>
|
||||
<ul>
|
||||
<li>Log messages are being displayed on the system console even
|
||||
though the log level for the console is set properly according to <a
|
||||
href="FAQ.htm#faq16">FAQ 16</a>. This problem may be corrected by
|
||||
installing <a
|
||||
href="ftp://ftp1.shorewall.net/pub/shorewall/errata/1.4.4a/firewall"
|
||||
target="_top">this firewall script</a> in
|
||||
/usr/share/shorewall/firewall
|
||||
as described above.<br>
|
||||
</li>
|
||||
</ul>
|
||||
<h3>1.4.4<br>
|
||||
</h3>
|
||||
<ul>
|
||||
<li> If you have zone names that are 5 characters long, you may
|
||||
experience problems starting Shorewall because the --log-prefix in a
|
||||
logging rule is too long. Upgrade to Version 1.4.4a to fix this
|
||||
problem..</li>
|
||||
</ul>
|
||||
<h3>1.4.3</h3>
|
||||
<ul>
|
||||
<li>The LOGMARKER variable introduced in version 1.4.3 was intended
|
||||
to allow integration of Shorewall with Fireparse
|
||||
(http://www.firewparse.com). Unfortunately, LOGMARKER only solved part
|
||||
of the integration problem. I have implimented a new LOGFORMAT variable
|
||||
which will replace LOGMARKER which has completely solved this problem
|
||||
and is currently in production with fireparse here at shorewall.net.
|
||||
The
|
||||
updated files may be found at <a
|
||||
href="ftp://ftp1.shorewall.net/pub/shorewall/errata/1.4.3/fireparse/"
|
||||
target="_top">ftp://ftp1.shorewall.net/pub/shorewall/errata/1.4.3/fireparse/</a>.
|
||||
See the 0README.txt file for details.<br>
|
||||
</li>
|
||||
</ul>
|
||||
<h3>1.4.2</h3>
|
||||
<ul>
|
||||
<li>When an 'add' or 'delete' command is executed, a temporary
|
||||
directory created in /tmp is not being removed. This problem may be
|
||||
corrected by installing <a
|
||||
href="ftp://ftp.shorewall.net/pub/shorewall/errata/1.4.2/firewall"
|
||||
target="_top">this firewall script</a> in
|
||||
/usr/share/shorewall/firewall
|
||||
as described above. <br>
|
||||
</li>
|
||||
</ul>
|
||||
<h3>1.4.1a, 1.4.1 and 1.4.0</h3>
|
||||
<ul>
|
||||
<li>Some TCP requests are rejected in the 'common' chain with an ICMP
|
||||
port-unreachable response rather than the more appropriate TCP RST
|
||||
response. This problem is corrected in <a
|
||||
href="ftp://ftp.shorewall.net/pub/shorewall/errata/1.4.1a/common.def"
|
||||
target="_top">this updated common.def file</a> which may be installed
|
||||
in /etc/shorewall/common.def.<br>
|
||||
</li>
|
||||
</ul>
|
||||
<h3>1.4.1</h3>
|
||||
<ul>
|
||||
<li>When a "shorewall check" command is executed, each "rule"
|
||||
produces the harmless additional message:<br>
|
||||
<br>
|
||||
/usr/share/shorewall/firewall: line 2174: [: =:
|
||||
unary operator
|
||||
expected<br>
|
||||
<br>
|
||||
You may correct the problem by installing <a
|
||||
href="ftp://ftp.shorewall.net/pub/shorewall/errata/1.4.1/firewall"
|
||||
target="_top">this corrected script</a> in
|
||||
/usr/share/shorewall/firewall as described above.<br>
|
||||
</li>
|
||||
</ul>
|
||||
<h3>1.4.0</h3>
|
||||
<ul>
|
||||
<li>When running under certain shells Shorewall will attempt to
|
||||
create ECN rules even when /etc/shorewall/ecn is empty. You may either
|
||||
just remove /etc/shorewall/ecn or you can install <a
|
||||
href="http://www.shorewall.net/pub/shorewall/errata/1.4.0/firewall">this
|
||||
correct script</a> in /usr/share/shorewall/firewall as described above.<br>

<h3><a name="Debug"></a>Problems with kernels >= 2.4.18 and RedHat
|
||||
iptables</h3>
|
||||
<blockquote>
|
||||
<p>Users who use RedHat iptables RPMs and who upgrade to kernel
|
||||
2.4.18/19 may experience the following:</p>
|
||||
<blockquote>
|
||||
<pre># shorewall start<br>Processing /etc/shorewall/shorewall.conf ...<br>Processing /etc/shorewall/params ...<br>Starting Shorewall...<br>Loading Modules...<br>Initializing...<br>Determining Zones...<br>Zones: net<br>Validating interfaces file...<br>Validating hosts file...<br>Determining Hosts in Zones...<br>Net Zone: eth0:0.0.0.0/0<br>iptables: libiptc/libip4tc.c:380: do_check: Assertion<br>`h->info.valid_hooks == (1 << 0 | 1 << 3)' failed.<br>Aborted (core dumped)<br>iptables: libiptc/libip4tc.c:380: do_check: Assertion<br>`h->info.valid_hooks == (1 << 0 | 1 << 3)' failed.<br>Aborted (core dumped)<br></pre>
|
||||
</blockquote>
|
||||
<p>The RedHat iptables RPM is compiled with debugging enabled but the
|
||||
user-space debugging code was not updated to reflect recent changes in
|
||||
the Netfilter 'mangle' table. You can correct the problem by installing
|
||||
<a
|
||||
href="http://www.shorewall.net/pub/shorewall/iptables-1.2.5-1.i386.rpm">
|
||||
this iptables RPM</a>. If you are already running a 1.2.5 version of
|
||||
iptables, you will need to specify the --oldpackage option to rpm
|

(e.g., "iptables -Uvh --oldpackage iptables-1.2.5-1.i386.rpm").</p>

|

<h3><a name="SuSE"></a>Problems installing/upgrading RPM on SuSE</h3>
|
||||
<p>If you find that rpm complains about a conflict with kernel <=
|
||||
2.2 yet you have a 2.4 kernel installed, simply use the "--nodeps"
|
||||
option to rpm.</p>
|
||||
<p>Installing: rpm -ivh --nodeps <i><shorewall rpm></i></p>
|
||||
<p>Upgrading: rpm -Uvh --nodeps <i><shorewall rpm></i></p>
|
||||
<h3><a name="Multiport"></a><b>Problems with iptables version 1.2.7 and
|
||||
MULTIPORT=Yes</b></h3>
|
||||
<p>The iptables 1.2.7 release of iptables has made an incompatible
|
||||
change to the syntax used to specify multiport match rules; as a
|
||||
consequence, if you install iptables 1.2.7 you must be running
|
||||
Shorewall
|
||||
1.3.7a or later or:</p>
|
||||
<ul>
|
||||
<li>set MULTIPORT=No in /etc/shorewall/shorewall.conf; or </li>
|
||||
<li>if you are running Shorewall 1.3.6 you may install <a
|
||||
href="http://www.shorewall.net/pub/shorewall/errata/1.3.6/firewall">
|
||||
this firewall script</a> in /usr/lib/shorewall/firewall as described
|
||||
above.</li>
|
||||
</ul>
|
||||
<h3><a name="NAT"></a>Problems with RH Kernel 2.4.18-10 and NAT<br>
|
||||
</h3>
|
||||
/etc/shorewall/nat entries of the following form will result in
|
||||
Shorewall being unable to start:<br>
|
||||
<br>
|
||||
<pre>#EXTERNAL INTERFACE INTERNAL ALL INTERFACES LOCAL<br>192.0.2.22 eth0 192.168.9.22 yes yes<br>#LAST LINE -- ADD YOUR ENTRIES ABOVE THIS LINE -- DO NOT REMOVE</pre>
|
||||
Error message is:<br>
|
||||
<pre>Setting up NAT...<br>iptables: Invalid argument<br>Terminated<br><br></pre>
|
||||
The solution is to put "no" in the LOCAL column. Kernel support for
|
||||
LOCAL=yes has never worked properly and 2.4.18-10 has disabled it. The
|
||||
2.4.19 kernel contains corrected support under a new kernel
|
||||
configuraiton option; see <a href="Documentation.htm#NAT">http://www.shorewall.net/Documentation.htm#NAT</a><br>
|
||||
<br>
|

<h3><a name="REJECT"></a><b> Problems with RH Kernels after 2.4.20-9
|
||||
and
|
||||
REJECT (also applies to 2.4.21-RC1)</b></h3>
|
||||
Beginning with errata kernel 2.4.20-13.9, "REJECT --reject-with
|
||||
tcp-reset" is broken. The symptom most commonly seen is that REJECT
|
||||
rules act just like DROP rules when dealing with TCP. A kernel patch
|
||||
and
|
||||
precompiled modules to fix this problem are available at <a
|
||||

intended to allow integration of Shorewall with Fireparse

part of the integration problem. I have implimented a new LOGFORMAT

this problem and is currently in production with fireparse here at
