Thanks again Jakes147, much appreciated, it seems to be working fine ('cept for the data leak/trickle issue.)
Last question: This seems to hinge on having an Internet Gateway in network connections, although none of the solutions I've looked at thru Google make mention of an Internet Gateway or even putting in a default gateway address, although mine doesn't seem to work without one? (I've set the laptop to obtain ip to auto. and it seems to create this gateway itself)
Edit: seemed to have stop the "leak" by disabling UPnP Device Host and SSDP Discovery Service in services.msc - will see if that causes any issues itself.
