My wxp box comes with PG3.4b, AppDefend 1.110, KAV6, Ghostwall 1.150, PE2.110. Today, again, we config the router to have port forwarding to my box for port range 1-65535, then give it a port probe test at grc.com. Can you see what is going on looking at the attachment! Any ideas! Is it a mistakes with ghostwall rule set? I try some port probe tests, the results are inconistent; anyway, ports are open according to the tests. * UPDATE : after trial-error, it seems that the wireless router netgear behaves incorrectly in that setting; and the test results are router's; Not ghostwall cause! Any idea? thx.
