Hello isalist, Hello once again! :o) Today I've tested my network through www.symantec.com and www.grc.com. They a saying strange things... I've got open ports 135 (DCE endpoint resolution) and 1723 (pptp)... But I did not want them to be opened... I do not want any ports to be opened to outside, exept ports used by my software from dynamic range. I mean I do not have any services that should be visible to outsiders. What can I do to fix that? And one more thing... All other ports were reported as "Closed", exept ICMP Ping and Port 80, which are "Stealth". How can I make all other ports "Stealth"? -- Best regards, Dennis V.
