    I've not expected LnS to do filtering at such low level that my network card does not even receive unwanted packets! That's pretty good for me.
    Now when i try to sniff the network in promiscous mode with Ethereal i see no packets.
    So i have added the following rule to solve this problem:
    Permit all packets having IPs and MACs NOT EQUAL to mine in both SOURCE and DEST modes.
    Will this rule be secure? Can it be a hole for packet flood?

    Does disabling promiscuous mode help? Have you selected the correct adaptor?
    Some more details on connection type, OS and LnS version might help troubleshoot this.
    Sounds like a permit all rule which would not be a good thing. Can you post a screen shot or full details of the rule?
