 5)  Previously, specifying a TYPE in /etc/shorewall/tcinterfaces would
     cause start/restart to fail on systems lacking 'flow' classifier

-    simply ignore the TYPE setting. In particular, RHEL5 and

+    There are two caveats:
+
+    - 'tc' may support 'flow' but the kernel does not. In that case,
+      start/restart will still fail.

+      file using shorewall-lite 4.4.7 in order for 'flow' to be

+      compiler will use other hints to try to determine if 'flow' is
