+# Test
+
+Check the expected default behavior for Exception Policies in IPS, in Suricata
+versions 6 and 7.

+# Behavior
+
+In 7, the auto behavior is to drop-packet and/or drop-flow in case of traffic
+exceptions, in IPS mode. In 6, the default behavior is to 'ignore'.
+
+# Pcap
+
+Pcap is the result of a curl to www.testmyids.com, later extracted with
