<h3>Version 1.3.14</h3>
|
||
|
||
<ul>
|
||
<li>There is an <a
|
||
href="http://www.shorewall.net/pub/shorewall/errata/1.3.14/rfc1918">updated
|
||
rfc1918</a> file that reflects the resent allocation of 222.0.0.0/8 and
|
||
223.0.0.0/8.</li>
|
||
|
||
</ul>
|
||
|
||
<ul>
|
||
<li>The documentation for the routestopped file claimed that a comma-separated
|
||
list could appear in the second column while the code only supported a
|
||
single host or network address.</li>
|
||
<li>Log messages produced by 'logunclean' and 'dropunclean' were not
|
||
rate-limited.</li>
|
||
<li>802.11b devices with names of the form <i>wlan</i><n> don't
|
||
support the 'maclist' interface option.</li>
|
||
<li>Log messages generated by RFC 1918 filtering are not rate limited.</li>
|
||
<li>The firewall fails to start in the case where you have "eth0 eth1"
|
||
in /etc/shorewall/masq and the default route is through eth1.<br>
|
||
</li>
|
||
|
||
</ul>
|
||
These problems have been corrected in <a
|
||
href="http://www.shorewall.net/pub/shorewall/errata/1.3.14/firewall">this
|
||
firewall script</a> which may be installed in /usr/lib/shorewall as described
|
||
above.<br>
|
||
|
||
<h3>Version 1.3.13</h3>
|
||
|
||
<ul>
|
||
<li>The 'shorewall add' command produces an error message referring
|
||
to 'find_interfaces_by_maclist'.</li>
|
||
<li>The 'shorewall delete' command can leave behind undeleted rules.</li>
|
||
<li>The 'shorewall add' command can fail with "iptables: Index of
|
||
insertion too big".<br>
|
||
</li>
|
||
|
||
</ul>
|
||
All three problems are corrected by <a
|
||
href="http://www.shorewall.net/pub/shorewall/errata/1.3.13/firewall">this
|
||
firewall script</a> which may be installed in /usr/lib/shorewall as described
|
||
above.<br>
|
||
|
||
<ul>
|
||
<li>VLAN interface names of the form "eth<i>n</i>.<i>m</i>" (e.g.,
|
||
eth0.1) are not supported in this version or in 1.3.12. If you need such
|
||
support, post on the users list and I can provide you with a patched version.<br>
|
||
</li>
|
||
|
||
</ul>
|
||
|
||
<h3>Version 1.3.12</h3>
|
||
|
||
<ul>
|
||
<li>If RFC_1918_LOG_LEVEL is set to anything but ULOG, the effect
|
||
is the same as if RFC_1918_LOG_LEVEL=info had been specified. The problem
|
||
is corrected by <a
|
||
href="http://www.shorewall.net/pub/shorewall/errata/1.3.12/firewall">this
|
||
firewall script</a> which may be installed in /usr/lib/shorewall as described
|
||
above.</li>
|
||
<li>VLAN interface names of the form "eth<i>n</i>.<i>m</i>" (e.g.,

eth0.1) are not supported in this version or in 1.3.13. If you need such

|
||
</li>
|
||
|
||
</ul>
|
||
|
||
<h3>Version 1.3.12 LRP</h3>
|
||
|
||
<ul>
|
||
<li>The .lrp was missing the /etc/shorewall/routestopped file
|
||
-- a new lrp (shorwall-1.3.12a.lrp) has been released which corrects this
|
||
problem.<br>
|
||
</li>
|
||
|
||
</ul>
|
||
|
||
<h3>Version 1.3.11a</h3>
|
||
|
||
<ul>
|
||
<li><a
|
||
href="http://www.shorewall.net/pub/shorewall/errata/1.3.11/rfc1918">This
|
||
copy of /etc/shorewall/rfc1918</a> reflects the recent allocation of
|
||
82.0.0.0/8.<br>
|
||
</li>
|
||
|
||
</ul>
|
||
|
||
<h3>Version 1.3.11</h3>
|
||
|
||
<ul>
|
||
<li>When installing/upgrading using the .rpm, you may receive
|
||
the following warnings:<br>
|
||
<br>
|
||
<20><><EFBFBD><EFBFBD> user teastep does not exist - using root<br>
|
||
<20><><EFBFBD><EFBFBD> group teastep does not exist - using root<br>
|
||
<br>
|
||
These warnings are harmless and may be ignored. Users downloading
|
||
the .rpm from shorewall.net or mirrors should no longer see these warnings
|
||
as the .rpm you will get from there has been corrected.</li>
|
||
<li>DNAT rules that exclude a source subzone (SOURCE column
|
||
contains ! followed by a sub-zone list) result in an error message and
|
||
Shorewall fails to start.<br>
|
||
<br>
|
||
Install <a
|
||
href="http://www.shorewall.net/pub/shorewall/errata/1.3.11/firewall">this
|
||
corrected script</a> in /usr/lib/shorewall/firewall to correct this
|
||
problem. Thanks go to Roger Aich who analyzed this problem and provided
|
||
a fix.<br>
|
||
<br>
|
||
This problem is corrected in version 1.3.11a.<br>
|
||
</li>
|
||
|
||
</ul>
|
||
|
||
<h3>Version 1.3.10</h3>
|
||
|
||
<ul>
|
||
<li>If you experience problems connecting to a PPTP server
|
||
running on your firewall and you have a 'pptpserver' entry in /etc/shorewall/tunnels,
|
||
<a
|
||
href="http://www.shorewall.net/pub/shorewall/errata/1.3.10/firewall">this
|
||
version of the firewall script</a> may help. Please report any cases
|
||
where installing this script in /usr/lib/shorewall/firewall solved your
|
||
connection problems. Beginning with version 1.3.10, it is safe to save
|
||
the old version of /usr/lib/shorewall/firewall before copying in the
|
||
new one since /usr/lib/shorewall/firewall is the real script now and
|
||
not just a symbolic link to the real script.<br>
|
||
</li>
|
||
|
||
</ul>
|
||
|
||
<h3>Version 1.3.9a</h3>
|
||
|
||
<ul>
|
||
<li> If entries are used in /etc/shorewall/hosts and MERGE_HOSTS=No
|
||
then the following message appears during "shorewall [re]start":</li>
|
||
|
||
</ul>
|
||
|
||
<pre> recalculate_interfacess: command not found<br></pre>
|

|
||
corrects this problem.Copy the script to /usr/lib/shorewall/firewall
|

as described above.<br>
|
||
</blockquote>
|
||
|
||
<blockquote> Alternatively, edit /usr/lob/shorewall/firewall and change the
|
||
single occurence (line 483 in version 1.3.9a) of 'recalculate_interefacess'
|
||
to 'recalculate_interface'. <br>
|
||
</blockquote>
|
||
|
||
<ul>
|
||
<li>The installer (install.sh) issues a misleading message
|
||
"Common functions installed in /var/lib/shorewall/functions" whereas
|
||
the file is installed in /usr/lib/shorewall/functions. The installer
|
||
also performs incorrectly when updating old configurations that had the
|
||
file /etc/shorewall/functions. <a
|
||
href="ftp://ftp.shorewall.net/pub/shorewall/errata/1.3.9/install.sh">Here
|
||
is an updated version that corrects these problems.<br>
|
||
</a></li>
|
||
|
||
</ul>
|
||
|
||
<h3>Version 1.3.9</h3>
|
||
<b>TUNNELS Broken in 1.3.9!!! </b>There is an updated
|
||
firewall script at <a
|
||
href="ftp://www.shorewall.net/pub/shorewall/errata/1.3.9/firewall"
|
||
target="_top">ftp://www.shorewall.net/pub/shorewall/errata/1.3.9/firewall</a>
|
||
-- copy that file to /usr/lib/shorewall/firewall as described above.<br>
|
||
<br>
|
||
Version 1.3.8
|
||
<ul>
|
||
<li> Use of shell variables in the LOG LEVEL or SYNPARMS
|
||
columns of the policy file doesn't work.</li>
|
||
<li>A DNAT rule with the same original and new IP
|
||
addresses but with different port numbers doesn't work (e.g., "DNAT
|
||
loc dmz:10.1.1.1:24 tcp 25 - 10.1.1.1")<br>
|
||
</li>
|
||
|
||
</ul>
|
||
Installing <a
|
||
href="http://www.shorewall.net/pub/shorewall/errata/1.3.8/firewall">
|
||
this corrected firewall script</a> in /var/lib/shorewall/firewall
|
||
as described above corrects these
|
||
problems.
|
||
<h3>Version 1.3.7b</h3>
|
||
|
||
<p>DNAT rules where the source zone is 'fw' ($FW) result in an error
|
||
message. Installing <a
|
||
href="http://www.shorewall.net/pub/shorewall/errata/1.3.7/firewall">
|
||
this corrected firewall script</a> in /var/lib/shorewall/firewall
|
||
as described above corrects this
|
||
problem.</p>
|
||
|
||
<h3>Version 1.3.7a</h3>
|
||
|
||
<p>"shorewall refresh" is not creating the proper rule for FORWARDPING=Yes.
|
||
Consequently, after "shorewall refresh", the firewall will not
|
||
forward icmp echo-request (ping) packets. Installing
|
||
<a
|
||
href="http://www.shorewall.net/pub/shorewall/errata/1.3.7/firewall">
|
||
this corrected firewall script</a> in /var/lib/shorewall/firewall
|
||
as described above corrects this
|
||
problem.</p>
|
||
|
||
<h3>Version <= 1.3.7a</h3>
|
||
|
||
<p>If "norfc1918" and "dhcp" are both specified as options on a
|
||
given interface then RFC 1918 checking is occurring before DHCP
|
||
checking. This means that if a DHCP client broadcasts using
|
||
an RFC 1918 source address, then the firewall will
|
||
reject the broadcast (usually logging it). This
|
||
has two problems:</p>
|
||
|
||
<ol>
|
||
<li>If the firewall
|
||
is running a DHCP server, the client
|
||
won't be able to obtain an IP address lease from
|
||
that server.</li>
|
||
<li>With this order
|
||
of checking, the "dhcp" option
|
||
cannot be used as a noise-reduction measure where there are both
|
||
dynamic and static clients on a LAN segment.</li>
|
||
|
||
</ol>
|
||
|
||
<p> <a
|
||
href="http://www.shorewall.net/pub/shorewall/errata/1.3.7/firewall">
|
||
This version of the 1.3.7a firewall script </a>
|
||
corrects the problem. It must be installed
|
||
in /var/lib/shorewall as described
|
||
above.</p>
|
||
|
||
<h3>Version 1.3.7</h3>
|
||
|
||
<p>Version 1.3.7 dead on arrival -- please use version 1.3.7a and check

|
||
must add an entry to /etc/shorewall/interfaces. Shorewall 1.3.3

and later versions produce a clearer error message in this
|
||
case.</p>

<p align="left">Until approximately 2130 GMT on 17 June 2002, the download

|

<li>When an option is given for more

than one interface in /etc/shorewall/interfaces then

depending on the option, Shorewall may ignore all but

the first appearence of the option. For example:<br>

loc<6F><63><EFBFBD> eth1<68><31><EFBFBD> dhcp<br>

<br>
|

Shorewall will ignore the 'dhcp' on eth1.</li>
|

<li>Update 17 June 2002 - The bug described

in the prior bullet affects the following options:

dhcp, dropunclean, logunclean, norfc1918, routefilter,

<h3><a name="Debug"></a>Problems with kernels >= 2.4.18

|
||
|
||
<blockquote>
|
||
<p>Users who use RedHat iptables RPMs and who upgrade to kernel 2.4.18/19
|
||
may experience the following:</p>
|
||
|
||
<blockquote>
|
||

</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>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>
|

<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>
