<li>(This change is in 1.4.3 but is not documented) If you are running
iptables 1.2.7a and kernel 2.4.20, then Shorewall will return reject replies
as follows:<br>
   a) tcp - RST<br>
   b) udp - ICMP port unreachable<br>
   c) icmp - ICMP host unreachable<br>
   d) Otherwise - ICMP host prohibited<br>
If you are running earlier software, Shorewall will follow it's traditional
convention:<br>
   a) tcp - RST<br>
   b) Otherwise - ICMP port unreachable</li>
<li>UDP port 135 is now silently dropped in the common.def chain.
Remember that this chain is traversed just before a DROP or REJECT policy
is enforced.<br>

This version primarily corrects the documentation included in the .tgz and
in the .rpm. In addition: <br>
<ol>
<li>(This change is in 1.4.3 but is not documented) If you are running
iptables 1.2.7a and kernel 2.4.20, then Shorewall will return reject replies
as follows:<br>
   a) tcp - RST<br>
   b) udp - ICMP port unreachable<br>
   c) icmp - ICMP host unreachable<br>
   d) Otherwise - ICMP host prohibited<br>
If you are running earlier software, Shorewall will follow it's traditional
convention:<br>
   a) tcp - RST<br>
   b) Otherwise - ICMP port unreachable</li>
<li>UDP port 135 is now silently dropped in the common.def chain.
Remember that this chain is traversed just before a DROP or REJECT policy
is enforced.<br>
