after setting Log info or log debug stdout.. i didnt get any info for the adapters. tor connects to the network and only
references 127.0.0.1 with "Notice"

"[Notice] Opening Socks listener on 127.0.0.1:xxxx"


"DisableIOCP 0/1" wont push away tor connecting to 18... either but i tried just in case to see if the behavior from
IOCP networking API would affect the connection.

yes blocking the ip does the trick for the fw while tor connects to the network.


thank you for the explanation.
