Need some help with double NAT config

Question, is how do I configure the Netgear Port Forward and the Calix Port Foward jointly so Tablo can get through the Double NAT?

The solution depends on the capabilities of the Calix device.

• If the Calix supports Port Forwarding, then simply:
  • On the Calix, forward those two ports to the Orbi IP (192.168.0.2) with the same port numbers (21145 and 21144)
  • On the Orbi, forward those two ports to the TVs IP as instructed (21145 to 8887 and 21144 to 80) . (Port forwarding must have a destination IP.)
  • I have done this through three routers.
• To avoid having to go through this process over and over again with other applications, the most common advice would be to turn one of the routers into "not a router", i.e.
  • Put the Calix into "bridge" or "modem only" mode.  This allows the Orbi to be the only router, so ports have to be forwarded only once.
  • Put the Orbi into Access Point (AP) mode.  This turns off all of the router functions, including DHCP serving, Armor, Parental Controls, port forwarding, VPN, etc. Then the Port Forwarding must be done on the Calix.

• If the Calix does not support Port Forwarding but does support DMZ, then you could try putting the Orbi's IP into the Calix DMZ.

I am not confident that putting the Tablo in the Orbi's DMZ will work because of the need to change port numbers.
