I went to the ShieldsUP!!! site and ran the file sharing and common ports tests. According to the results, I allowed ping to reply to their server via ICMP echo, and I have port 21 (ftp) and 23 (telnet) open. How do I: (1) block/ignore ICMP echo requests (2) Tell inquirers that ports 21 and 23 exist but are closed to connections Thanks for the feedback. John Dangler
