I am a little confused this morning...
I have a networked DVR on my home network address 192.168.2.*. I have the 4GEE mobile router with a public IP address in my roof space of 213.205.198.*** as reported by whatsmyip.com. WAN ping is enabled. This router has a local LAN IP of 192.168.11.1 and feeds another cable type router downstairs by CAT6. It gets its "WAN" IP from the 4GEE router and is confirmed sensible at 192.168.11.2**. This second router uses NAT to give me final LAN addresses in the 192.168.2.* subnet.
I cannot get a connection to the DVR. Ports are 37777 and 80.
I have tried to break it down into stages and so far I have been unable to get a ping return from the WAN address. I have no useful options on that 4G router, so have tried setting the DMZ to the "WAN" address of router 2. My belief is that it should then transparently pass everything through. I have no ping option on router 2, so no test available there. All I can do at that point is rely on the port forwarding on router 2 to connect with the DVR, which doesn't happen.
I have done a little research and it appears that the 4G routers use Carrier Grade NAT which is a sort of double private IP translation. Not come across that before, but I would have thought that it would be transparent to what I am trying to do.
Any tips?
