Hi, Just switched over to Kerio this afternoon...it past port probe tests on GRC and some tests on PC Flank, but then on the quick test I got the following warning: The test found visible port(s) on your system: 80 Recommendation: Install personal firewall software. If you have already installed and are using a firewall, check if it is set to make all the ports of your computer invisible (hidden). If it is, then get new firewall software and redo this test. Sorry, I know this is a dumb question, but I'm learning here... What rule can I type in to Kerio to make all ports on my computer invisible (stealthed), hidden...? Thanks!
