Michael, there have been a number of conversations with members of my
team, the network group, and the Chief Information Security Officer
regarding this request.

As previously noted, we cannot unblock port 6667 as this increases our
security exposure.  Unfortunately we also cannot open up all of the
sites you requested either.  My next suggestions would be to narrow your
list to ten or fewer sites and give us the internal addresses that need
the access.

I sent you the request for specific addresses as you specified in the
e-mail
I am replying to on 8/30/06 . It has been over a month and none of the
requests have been implemented. What is the ETA for the requests to be
implemented? Thanks.

Michael Ross
