It appears to be a standard practice for Cable Company run broadband.

My previous QTH broadband ISP actually stated that they were doing this 
in their TOS document.

My NATing router does not have that feature.

Not sure if the only other ISP would be any better.

I did a test last night and did not connect to RAT1 in addition to RAT. 
  RAT was active most of the night and I did not see the CPU utilization 
until this morning when the GUI was no longer responding.

I have started a QST beacon on RAT, and will monitor it tonight.
