Due to an increasing number of intrusions into windows-based machines
through unprotected shares, I've started filtering both incoming and
outgoing traffic for our customers on ports 138/139.
So far this has caught a fair amount of traffic coming from customers,
but none have called to complain about a lack of connectivity.
Because this traffic is IP traffic, I wanted to ask others on this list
how they treat SMB traffic on their backbones?
Thanks
