How to properly setup WireGuard LXC via public IP

[GudBoiNero]

Ok so I've tried to setup the WireGuard LXC multiple times in the past month or two. Once it just didn't work, the other times it worked- meaning I could use my VPN and access the internet, but for some godforsaken reason I could never get access to local IPs (192.168.1.x).

Setup

After I set the LXC up, I port forward my router's port 51820 to my WireGuard LXC's 192.168.1.x:51820.

Then I go into WGDashboard and set the Peer Settings endpoint to my public IP.

I go into wg0 config and set the CIDR to 10.32.0.1/24

Then I create a peer and it sets the Addresses to 10.32.0.2/32

At this point I scan the QR code on my phone to connect- and then I enable my VPN, turn off WiFi, turn on Cellular, and try to connect to 192.168.1.233:9000 (my portainer instance). It doesn't work. Yet somehow everything else that isn't my local network does work. Like YouTube and Google.

I had a feeling that this had something to do with my Endpoint Allowed Addresses and so I tested out multiple configurations:
0.0.0.0/0,192.168.1.0/24
10.32.0.2/32
Mind you I really have not much of a clue how CIDR works, so this is also just guessing with colleagues and GPT. I would really love some help here.

If I try to ping my phone on WGDashboard at this point, it says my pings went through and I'm connected, it even picks up that I'm using data and shows it on the graph.

If I use shell in my LXC and ping 192.168.1.233: it works. nc -z or the other command to test ports also works with this IP at port 9000.

So at this point I'm really confused what's wrong. I've been troubleshooting this for weeks in intervals and I cannot understand what's wrong.

Help appreciated.
