+ * MXS-2037: Wildcards not working with source in NamedServerFilter
+ *
+ * https://jira.mariadb.org/browse/MXS-2037
+ *
+ * This test only tests that ip addresses with wildcards are accepted by
+ * NamedServerFilter. The actual matching functionality is not tested
+ * because the client IPs can change with the different test environments
+ * and that would make it complicated to check if the matching is correct.
