Hi, i'm a new user of CIS 5 and tested it against pcflank's firewall leaktest. I'm aware that these tests are not ultimate or the definite answer if a firewall is good or bad. My pc is behind a DSL-NAT-router. CIS firewall security level is on "custom". Anyway i got some questions: 1) The port scan says ports : 21, 23, 80, 135, 137, 138, 139, 1080, 3128 are open ? Except port "System / TCP : listening 138", i don't know why these ports appear as open ? 2) The trojan check show ports : 27374, 12345, 1243, 31337, 12348 as visible ? Thanks for any comments or answers.
