Connecting Nginx Server to OpenVPN and Accessing it from the Internet

I have an Nginx server running on my local network, and I want to make it accessible from the internet via an OpenVPN connection. Here are the details of my setup:

• Ubuntu Server Local IP Address: 192.168.29.110

• OpenVPN Access Server IP Address: 139.59.60.64

Notes:

1. OpenVPN Access Server is running on a DigitalOcean Ubuntu Server (called OpenVPN-server hereon)
2. Nginx is running on a local Ubuntu Server at home (called Nginx-server hereon)
3. Home network (ISP) doesn't allow dedicated IP / port forwarding due to which I'm unable to access my Nginx-server from outside the LAN network. Therefore the goal is to connect local Nginx-server to OpenVPN-server so as to use the IP address of the VPN connected and thereby allow Nginx-server to be accessible from the word wide web (public internet).
4. UFW is disabled on both OpenVPN-server as well as Nginx-server.
5. DigitalOcean firewall is disabled.

Network Configuration on Nginx-server:Netplan configuration (/etc/netplan/01-netcfg.yaml):

network:  ethernets:    eno1:      addresses:      - 192.168.29.110/24      nameservers:        addresses:        - 8.8.8.8        search: []      routes:      - to: default        via: 192.168.29.1  version: 2

Nginx Configuration on Nginx-server:Nginx configuration file (/etc/nginx/sites-available/default):

server {    listen 80;    listen [::]:80;    root /var/www/html;    index index.html index.htm index.nginx-debian.html;    server_name 139.59.60.64;    location / {        proxy_pass http://192.168.29.110;  # Update this line        include proxy_params;        proxy_http_version 1.1;        proxy_set_header Upgrade $http_upgrade;        proxy_set_header Connection "upgrade";    }

Challenges and Questions:

1. Replacing OpenVPN Dashboard with Nginx Landing Page:

• I currently access the OpenVPN Access Server dashboard from the IPaddress 139.59.60.64. After establishing a connection fromNginx-server to the OpenVPN-server, I want to replace the dashboardwith my local Nginx landing page. How can I achieve this?

2. Making Nginx Accessible from the Internet via OpenVPN:

• After connecting to the OpenVPN-server, what changes do I need to make in my Nginx configuration file and Netplan configuration on Nginx-server to access my Nginx-server from the internet?
