Apprec. the info.  Probes are falling off now.  25k in the last 6hrs
 (as of 1500hrs EST).

Not much in the grand scheme of things but more then I like.  A couple of
servers at this facility are being targeted - no sooner had I ACL'ed
one block when probes from a new block to the same targets surfaced.  In
any event, the target servers are offline pending a close inspection.

Thanks to all that responded,
