Hi there. First of all, I would like to say that Look'n'Stop is possible software we are going to buy, if it matches our needs. We need small firewall program, which could be installed & run on Windows 2000 Server via Remote Desktop Connection without blocking RDC port when installing (so we won't lose RDC possibility next time), and which allows easily import IP list which could be created in any other program. Until that, Look'n'Stop looks excellent and probably is the first program we have found, which provides everything above. The problem is, when we import rule called "Block a given IP" and set IP to the necessary, LnS blocks not only chosen IP, but the general web-traffic to the server on every IP. We are running IIS on this machine, and it looks like IIS is not responding anymore when this rule is imported & created. When it's removed, and LnS is restarted, IIS is working again. What could be the fault? Thank you.
