+
+  The sshguard update to 1.6.2 introduces a rewritten IPFW backend. The
+  previous approach was to insert individual block rules with a
+  predefined  numbered range. This does not scale well and is not
+  flexible so the design was scrapped. The new approach utilizes IPFW
+  tables. The sshguard IPFW backend now inserts offenders into hardcoded
+  table 22.
+
+  To continue blocking the attackers effectively you will need to add a
+  block rule like the following:
+
+  ipfw add deny all from 'table(22)' to any
+  
+  The release announcement can be found here:
