Share single service via WireGuard (feddit.it)

I wanted to share a service I'm hosting, but didn't feel comfortable just leaving publicly accessible, even behind a reverse proxy. In the meantime I did not want to give access to my whole lan with a VPN, or redirect all internet traffic from a client thru my network. So the idea is to run a WireGuard instance on my OpenWRT router in a completely isolated zone (input, output and forward set to reject on firewall) and then forward a single port from the service host's. Client is android, so using WG Tunnel and split tunnel just for the relevant app should not impair client's network access. Initial tests seems to be ok, is there anything I may have overlooked? Please feel free to comment.

Don't worry, there's no deadline here. I'm not sure I got it so I'll try to explain what I understood. You're saying that I have to set a single IP address for the client, and allow that single address to connect to service on port 8080 on 192.168.10.1 in the firewall, right? I'm not too confident in my ability to configure the firewall, so I thought that completely isolate the subnet 192.168.2.0 and then forward a single port to it was the safe choice.
