I have been running the free version 2.1.5 of Kerio for some time now with no problems, and have pretty much refined a set of rules which works to stealth my machine, but still lets me do whatever I need to do on the internet. Until recently .... I recently installed CCProxy on my machine, and my kids machine connects to the internet via this proxy server. However, I have just run a Shields Up test at GRC and have found several open ports much to my horror. I managed to close a couple of them by disabling things in my proxy server I didnt need, such as news and telnet, but I still have three ports open. Both mail ports - 110 and 25, and 808 - which is the default port my proxy server uses for most protocols. Can someone please tell me what to do to at the very least, close these three ports, or preferably - stealth them? I am not particularly knowledgeable about proxy servers as this is the first time I have used one, so chances are I may have made some rules errors in Kerio for the proxy server rules. I could post a screenshot of my kerio rules if that would help. Any help anyone can offer me would be much appreciated. TIA!
