how to ping :
I dont know which OS you have so Im gonna generalize. you can click on start, select run and type command. Once you get the prompt type this : ping 126.96.36.199 and hit enter. Of course, use IP that makes sense. if you dont get anywhere and your firewall is turned off, you have another problem. I think you have to add the IP of your remote PC to the trusted source, or a filter...I dont know how your firewall handles these. You probably have a firewall log so check it for the access from a LAN...it will probably tell you that unknown resource is trying to access the internet trough your PC every time you try to access. You might want to to Kerio website and find the F.A.Q to your product and comb trough, Im sure they have an explanation...if that fails, email their tech support with your question.
