I'm trying Look'n'Stop but the strange thing that happens is that the firewall seems to work ok for the first hours of work (nothing wrong!). After a few hours (it differs) it droppes every connection and blocks eveything. Unloading (exit) the firewall and restarting it makes no diference. Only a clean boot will solve the problem and i can work with it for a few hours again. I'm running Windows XP SP2 on a Dell D820 Laptop. Look'n'Stop log shows mainly UDP: Any other UDP packet and TCP: Any other packet, even when the detail of the packet shows that it is actualy only http (outgoing traffic); which shouldn't be blocked i suppose. Any one any suggestions??
