I am having an unusual problem between my content router and content engines.  Right now I have a basic configuration of 3 machines: CDM(cdm4650-5.0.1), CR( ce565-5.1.5), CE( ce565-5.1.5).  All three items are plugged into the same switch.  All machines are seen by my CDM gui. My problem is that my CR does not register my CE.  When I do " show statistics content-routing dns" I see that the CR has received 22744 keepalives:
#show statistics content-routing dns
----- CR DNS Statistics -----

    Content engine aliases   		:                  0
        Aliases for Down CEs  	:                  0
    Unknown domains          		:                  0

    From unknown source       	:                  6
However when I do "show statistics content-routing ce" the CR reports that the CE has sent no keepalives.  I only have one CE so I know the keep alives are coming from it.  In fact, I can do a "tcpdump port 53" and see the ip address of my CE sending the dns keepalives.

Has anyone had an issues like this when setting up their CDN?
