Descripción
*** Pendiente de traducción *** A regression in the way hashes were calculated caused rules containing the address range syntax (x.x.x.x - y.y.y.y) that only differ in the address range(s) involved to be silently dropped as duplicates. Only the first of such rules is actually loaded into pf. Ranges expressed using the address[/mask-bits] syntax were not affected.<br />
<br />
Some keywords representing actions taken on a packet-matching rule, such as &#39;log&#39;, &#39;return tll&#39;, or &#39;dnpipe&#39;, may suffer from the same issue. It is unlikely that users have such configurations, as these rules would always be redundant.<br />
<br />
Affected rules are silently ignored, which can lead to unexpected behaviour including over- and underblocking.
