I am still confused about this issue and need some reinforcement of
ramifications. If I go into my router's setup and block ports
135~139 and 445, I understand this will block access of these ports
to anything coming from outside of my NAT router.
But does blocking any of these ports interfere with netbios sharing
of my workgroup inside (behind the NAT but still going thru wireless
port on router ) my LAN ?
