<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
|
||||
<li>set MULTIPORT=No in
|
||||
/etc/shorewall/shorewall.conf; or </li>
|
||||
<li>if you are running Shorewall 1.3.6
|
||||
you may install

<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>

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
