Hi, I'm still in the trial period of Smart Security but I think that I will purchase a 2-User Pack soon. Yesterday a "New network detected" window appeared and told me to choose the protection mode of my computer in the network Subnet: 192.168.100.0 / 255.255.255.0. I was unable to access IE 7 until I ticked "Allow Sharing (not recommended)." Today, when I open Smart Security and select Setup > Change the protection mode of my computer in the network I see a window which informs me that "this computer is a member of several subnets. Select the subnet for which you want to change the protection mode:" Subnet: 169.254.0.0 / 255.255.0.0 Subnet: 220.127.116.11 / 255.255.255.0 Edit: I have found that if I tick Strict Protection for either Subnet my internet access is not impeded.
