I just wanted to expose my computer to my Lan I have at home. XP ICF by defaults stops that.
article has helped as i can use all the ips in my lan to allow browing on their User Datagram Protocol (UDP) ports from 135 through 139, and Transmission Control Protocol (TCP) ports from 135 through 139 and port 445
by specify only my lan ips will keep out all other.
thanks lbyard for that
