OK it was not the cable.  Nor was it my router.

I needed to set the guest network to bridged. Which I think I did.

Remember I told you I was paranoid?  Well the new VM has a static IP and 
that IP needed to be put into my Access Control List (ACL).  Yikes I 
chased that one for lots of hours.  Glad I finally figured that one out.
