I just purchased and installed my first Tablo. Everything is working correcting, but I’m trying to set up Tablo Connect for remote access. I’m getting the message that my router requires manual configuration.
On your router, the Netgear, what is the WAN IP? Is it an external IP or an internal IP?
Internal IPs start with 192., 10., or 172.
Assuming you are in some sort of bridge mode, I would just turn off UPnP on the Nighthawk and then turn it back on. Then turn on remote access on the Tablo. That works well for me.
