This issue is quite heated, just read a few threads from DSLReports.com and you
will see. Some people are happy to have us blocking everything, and some of our
customers even complain that we don't block certain things. Others see it as an
attempt to control and watch their every move.
Currenty, we are only blocking port 139, and there are about 2 dozen customers
who have opted out of it for various reasons. If we start blocking all the
other ports, we may find ourselves getting calls about mysterious problems that
can only be solved by un-blocking one or more of the ports for that customer.
Also, it may start being costly to the CPU on our gateway router if we have
hundreds of extra lines in our ACLs. Its handling pretty well so far, so that
may be moot, but it is something to consider.
