New Cable Modem - Port Forward Issue

Just got my new Xfi Gateway and hooked it up.   One of the computers on my LAN is an IP based home automation server.   I can access it from outside my LAN using the NoIP service.    It requires 3 ports to be forwarded to it and it requires a static IP.    All of this worked on the old Gateway and I configured the new Gateway similarly.   I have 3 clients on my LAN hitting the home automation server.     Got these results:

 

Surface tablet - hooked to network via WiFi - server not responding message

iPhone - hooked to network via WiFi - server not responding message

iPhone - hooked to network via cellular data  - able to access MyServer

desktop - hooked to network via ethernet cable - server not responding message

 

So it seems the port forwards aren't working, at least for devices connected on my LAN.    When my iPhone goes outside the LAN using cellular the port forwards work.    So it seems possible the new router is blocking something I haven't figured out yet.   I can't find a setting anywhere.    Or is it time to think about a new modem/router?

 

Thanks, Chris

I should mention Advanced Security is turned off.
