checking is occurring before DHCP checking. This

means that if a DHCP client broadcasts using an

reject the broadcast (usually logging it). This

<p>To properly upgrade with Shorewall version

1.3.3 and later:</p>
|
|
|
|
|
|
|
|
|
|
|
|
<ol>
|
|
|
|
|
|
<li>Be sure you have a backup -- you will need
|
|
|
|
|
|
to transcribe any Shorewall configuration
|
|
|
|
|
|
changes that you have made to the new
|
|
|
|
|
|
configuration.</li>
|
|
|
|
|
|
<li>Replace the shorwall.lrp package provided on
|
|
|
|
|
|
the Bering floppy with the later one. If you did
|
|
|
|
|
|
not obtain the later version from Jacques's
|
|
|
|
|
|
site, see additional instructions below.</li>
|
|
|
|
|
|
<li>Edit the /var/lib/lrpkg/root.exclude.list
|
|
|
|
|
|
file and remove the /var/lib/shorewall entry if
|
|
|
|
|

present. Then do not forget to backup root.lrp !</li>

<p>The .lrp that I release isn't set up for a two-interface firewall like

Jacques's. You need to follow the <a href="two-interface.htm">instructions for

<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>

<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

<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,
|
2002-08-27 00:17:49 +02:00
|
|
|

if you install iptables 1.2.7 you must be running
