+        <p>
+          If you have compiled your kernel with the <tt/IPFIREWALL/ 
+          option, you need to be aware that the default policy as of
+          2.1.5R (this actually changed during 2.1-STABLE development) 
+          is to deny all packets that are not explicitly allowed.
+
+        <p>
+          If you had unintentionally misconfigured your system for
+          firewalling, you can restore network operability by typing
+          the following while logged in as root:
+
+        <verb>
+     ipfw add 65534 allow all from any to any
+        </verb>
+
+          For further information on configuring a FreeBSD firewall,
+          see the <url url="http://www.freebsd.org/handbook/handbook.html" name="FreeBSD Handbook.">
