<h3>Version 1.3.10</h3>
|
||
If you have installed the 1.3.10 Beta 1 RPM and are now upgrading to version
|
||
1.3.10, you will need to use the '--force' option:<br>
|
||
<br>
|
||
<blockquote>
|
||
<pre>rpm -Uvh --force shorewall-1.3.10-1.noarch.rpm </pre>
|
||
</blockquote>
|
||
<h3>Version >= 1.3.9</h3>
|
||
The 'functions' file has moved to /usr/lib/shorewall/functions. If you
|
||
have an application that uses functions from that file, your application
|
||
will need to be changed to reflect this change of location.<br>
|
||
|
||
<h3>Version >= 1.3.8</h3>
|
||
|
||
<p>If you have a pair of firewall systems configured for failover
|
||
or if you have asymmetric routing, you will need to modify
|
||
your firewall setup slightly under Shorewall
|
||
versions >= 1.3.8. Beginning with version 1.3.8,
|
||
you must set NEWNOTSYN=Yes in your
|
||
/etc/shorewall/shorewall.conf file.</p>
|
||
|
||
<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<br> run_iptables -A icmpdef -p ICMP --icmp-type source-quench -j ACCEPT<br> run_iptables -A icmpdef -p ICMP --icmp-type destination-unreachable -j ACCEPT<br> run_iptables -A icmpdef -p ICMP --icmp-type time-exceeded -j ACCEPT<br> 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:<br># allow loc to fw udp/53 for dnscache to work<br># allow loc to fw tcp/80 for weblet to work<br>#<br>ACCEPT loc fw udp 53<br>ACCEPT loc fw tcp 80</pre>
|
||

|

<li>
