If you're doing it manually, you'll use a tool called Easy-RSA to create these cryptographic assets, which can be a bit more involved, so just be aware.
You'll also need to configure the OpenVPN server settings. This includes defining the IP address range for your private network, setting up DNS servers, and specifying the port for the VPN connection. These settings go into a configuration file, typically located in `/etc/openvpn/server.conf`. It's important to choose a strong encryption cipher and hash algorithm for the best security, you know, to keep things safe.
After configuring the server, you'll need to enable IP forwarding on your Raspberry Pi. This tells your Pi to act as a router, allowing traffic to pass between your private network and the wider internet. You can do this by editing the `sysctl.conf` file. This step is pretty crucial for your private network to work as expected, so don't forget it.
Securing Remote Access
