Configuring omr/vps

[openSourceBugs]

I am attempting to configure a static ip for the raspberry pi router. I was able to flash to a SD and boot the raspberry pi and see the openmptcprouter ascii art. It also seems like the vps script completed successfully. Right now I am stuck on the static ip/local networking side of things. I have a Sagecom fast 5290 modem from Frontier (los angeles based isp) that's connected to a Netgear R6400 router which plugs into the raspberry pi ethernet port.
I went into the netgear settings and set some dhcp settings.

I see that the raspberry pi is connected to the netgear router:

I go to 192.168.1.50 and get "connection refused". At one point I was able to get the web application to load, add the keys form the script (I see cp: can't create /etc/unbound/root.key errors in the pi indicating the functionality worked at one point). I got the "duplicate interface" errors so thought it was something about the DHCP problems I read about. When I went to configure this now I can't ssh or get the web application to show up.

Somehow the SD card became corrupted and became write-only. I reflashed and was able to get back the web interface. For the lan settings, i'm assuming:

I'm not sure how to even connect the wifi of the pi to a mobile hotspot on my phone in openwrt. Seems like a complicated command line filled process.

https://openwrt.org/docs/guide-user/network/wifi/connect_client_wifi I did find this resource but it just confused me more. I found the network I wanted to connect to and entered the password but don't know how to configure the interface to be used as an additional path.

Managed to get to this point. I'm not sure what to do about the errors.

I see that there's a gateway and an ip address assigned to the phone but these do not seem to resolve the errors. I checked the interface as well and made it a static ip. After changing it to dhcp, the error seems to have gone away.
I am guessing the next step is to test how this works and how to route traffic through the netgear router to the raspberry pi, and have the pi route back through the pi and the wireless device.
