If you allow established communications but not new communications before
your blocks then your users will never know that you are blocking all new
communications from those IP spaces because when they request communication
to one of those IPs they will get the responds back.

Subject: [WISPA] informing customers of internal issues
A few weeks ago we has a DOS attack from an Asian network. I quickly
blocked the whole range addresses and the issue went away. Apparently,
the range contained some web hosts with sites that are visited by one
of my customers. I found this out when they asked for assistance. I
unblocked the range and all is OK and no DOS attacks (yet). This
customer asked if I could inform him when this type of issues arises.
Obviously, it would be impossible for me to know if it affected any
websites. Also, even if I knew which website, I cant know who visits
them. Therefore, they asked if I can place any network changes on my
forums. I've got several issues with that. What do you guys do?
