    I am using a Belkin Router with built in firewall. The firewall has SPI built into the router. LooknStop works fine with the router, but should I switch on SPI in LooknStop as well, or will that mess up my Router working in conjunction with LooknStop?

    I have not had to set up any extra rules, at the moment, LnS just worked ok.

    :D

    The SPI in Look"n" Stop will work fine with the Belkin router - you will get the occasional log from L"n"S statefull inspection but this is nothing to worry about.

    Thanks for reply-I switched SPI on in LooknStop, and my uTorrent stopped downloading anything!

    Ive got the uTorrent rule set up and it all works except when I activate SPI in LooknStop.

    Maybe if I leave SPI off, I will still be protected enough, any ideas anyone? Thanks.

    :) :)

    From what i understand the SPI option just records unknown connections into the log. I just leave it off as i rarely ever check the log.

    Same problem here.
    So, does anyone know how necessary SPI is? Does disabling it reduce safety significantly?

    Well all it does is monitor packets and verifies that they belong to an active connection, if not it will display an alert in the log. If you regularly check your logs then its helpful to have it enabled.
