Nighthawk Remote Access With AT&T Arris NVG589 Modem
Hello, I am trying to use the Remote Access feature on my Nighthawk Router. Currently with Remote Access enabled I get these two IP addresses from the nighthawk: 192.168.1.X: port number and 2602:...

If you have IP Passthrough enabled, then your Nighthawk should be using the PUBLIC IP address assigned to your modem, not 192.168.1.200, which is a PRIVATE IP address.
If you log into the NVG589, go to Devices > Device List and you will see IP addresses assigned by the modem. It will clearly call out the device using IP Passthrough (which should be your Nighthawk) and its IP address. This IP address must match the Broadband Ipv4 Address shown on the Broadband Status page on the NVG589. Finally, this address must also show up as the Internet IP address on the Nighthawk's Basic > Internet page. If any of this is not true, then IP Passthrough is not set up correctly.

I will check when i get home today! also on the router i have it set for a static IP, should i have it set to obtain from isp?

It depends on the Passthrough mode setting. If it is set to either DHCP-Fixed or DHCP-Dynamic, then you should set the Nighthawk to obtain its IP address from the ISP. If it is set to Manual, then you should enter the modem's public IP address as the static IP address on the Nighthawk.
I use DHCP-Fixed. Should the modem's IP address change (a rare but not unheard of event), the Nighthawk will automatically pick it up after a few minutes.

I just got home. I went into my modem settings and made the dhcp range 192.X.X.X. and Rebooted. Then Went into my router and clicked get dynamically from isp. The Router Ip changed to 75.X.X.X. If i go to Modem Device list, it also lists this. I went to remote management under the router, and it lists this ip with the port number, but i still can't access my router from the cellular data on my phone. Alos under IP passthrough, its set to dhcp fixed, and i have my router's mac address in there.
