<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>
|
||
|
||
<h3 align="Left">Version >= 1.3.6</h3>
|
||
|
||
<p align="Left">If you have a pair of firewall systems configured for
|
||
failover, you will need to modify your firewall setup slightly under
|
||
Shorewall versions >= 1.3.6. </p>
|
||
|
||
<ol>
|
||
<li>
|
||
|
||
<p align="Left">Create the file /etc/shorewall/newnotsyn and in it add
|
||
the following rule<br>
|
||
<br>
|
||
<font face="Courier">run_iptables -A newnotsyn -j RETURN # So that the
|
||
connection tracking table can be rebuilt<br>
|
||
|
||
# from non-SYN packets after takeover.<br>
|
||
</font></li>
|
||
<li>
|
||
|
||
<p align="Left">Create /etc/shorewall/common (if you don't already
|
||
have that file) and include the following:<br>
|
||
<br>
|
||
<font face="Courier">run_iptables -A common -p tcp --tcp-flags
|
||
ACK,FIN,RST ACK -j ACCEPT #Accept Acks to rebuild connection<br>
|
||
|
||
#tracking table. <br>
|
||
. /etc/shorewall/common.def</font></li>
|
||
</ol>
|
||
|
||
<h3 align="Left">Versions >= 1.3.5</h3>
|
||
|
||
<p align="Left">Some forms of pre-1.3.0 rules file syntax are no
|
||
longer supported. </p>
|
||
|
||
<p align="Left">Example 1:</p>
|
||
|
||
<div align="left">
|
||
<pre> ACCEPT net loc:192.168.1.12:22 tcp 11111 - all</pre>
|
||
</div>
|
||
|
||
<p align="Left">Must be replaced with:</p>
|
||
|
||
<div align="left">
|
||
<pre> DNAT net loc:192.168.1.12:22 tcp 11111</pre>
|
||
</div>
|
||
<div align="left">
|
||
<p align="left">Example 2:</div>
|
||
<div align="left">
|
||
<pre> ACCEPT loc fw::3128 tcp 80 - all</pre>
|
||
</div>
|
||
<div align="left">
|

<p align="left">Must be replaced with:</div>
|
||
<div align="left">
|
||
<pre> REDIRECT loc 3128 tcp 80</pre>

||
</div>
|
||
|
||
<h3 align="Left">Version >= 1.3.2</h3>
|
||
|
||
<p align="Left">The functions and versions files together with the
|
||
'firewall' symbolic link have moved from /etc/shorewall to /var/lib/shorewall.
|
||
If you have applications that access these files, those applications
|
||
should be modified accordingly.</p>
