<h3>Version >= 1.3.7</h3>

|
|
<p>Users specifying ALLOWRELATED=No in
|
|||
|
|
/etc/shorewall.conf will need to include the
|
|||
|
|
following rules in their /etc/shorewall/icmpdef
|
|||
|
|
file (creating this file if necessary):</p>
|
|||
|
|
|
|||
|
|
<pre> run_iptables -A icmpdef -p ICMP --icmp-type echo-reply -j ACCEPT
|
|||
|
|
run_iptables -A icmpdef -p ICMP --icmp-type source-quench -j ACCEPT
|
|||
|
|
run_iptables -A icmpdef -p ICMP --icmp-type destination-unreachable -j ACCEPT
|
|||
|
|
run_iptables -A icmpdef -p ICMP --icmp-type time-exceeded -j ACCEPT
|
|||
|
|
run_iptables -A icmpdef -p ICMP --icmp-type parameter-problem -j ACCEPT</pre>
|
|||
|
|
<p>Users having an /etc/shorewall/icmpdef file may remove the ".
|
|||
|
|
/etc/shorewall/icmp.def" command from that file since the icmp.def file is now
|
|||
|
|
empty.</p>

<h3><b><a name="Bering">Upgrading </a>Bering to
|
|||
|
|
Shorewall >= 1.3.3</b></h3>
|
|||
|
|
|
|||
|
|
<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>
|
|||
|
|
</ol>
|
|||
|
|
<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
|
|||
|
|
setting up a two-interface firewall</a> plus you also need to add the following
|
|||
|
|
two Bering-specific rules to /etc/shorewall/rules:</p>
|
|||
|
|
<blockquote>
|
|||
|
|
<pre># Bering specific rules:
|
|||
|
|
# allow loc to fw udp/53 for dnscache to work
|
|||
|
|
# allow loc to fw tcp/80 for weblet to work
|
|||
|
|
#
|
|||
|
|
ACCEPT loc fw udp 53
|
|||
|
|
ACCEPT loc fw tcp 80</pre>
|
|||
|
|
</blockquote>

|||
