Step 3: Configure IP Address
Assign a static IP address to your Raspberry Pi to ensure it remains accessible within the network. This can be done through the Raspberry Pi OS network settings or via your router's configuration page.
Understanding Port Forwarding
Port forwarding is a crucial step when connecting Raspberry Pi behind a router. It allows external devices to access services running on your Raspberry Pi. Here's how you can set it up:
- Log in to your router's admin panel.
- Locate the port forwarding section.
- Add a new rule, specifying the external port, internal port, and IP address of your Raspberry Pi.
Best Practices for Port Forwarding
When configuring port forwarding, consider the following best practices:
- Use non-standard ports to enhance security.
- Limit access to specific IP ranges if possible.
- Regularly review and update your port forwarding rules to ensure they align with your current setup.
Network Configuration Basics
Understanding network configuration basics is essential for a successful setup. Here are some key concepts:
- Subnet Mask: Determines the range of IP addresses available on your network.
- Gateway: The IP address of your router, acting as the entry point to the internet.
- DNS Servers: Provide domain name resolution services.
Tips for Network Configuration
When configuring your network, keep the following tips in mind:
- Document your network settings for easy reference.
- Use a consistent naming convention for devices.
- Regularly update your router's firmware to ensure optimal performance and security.
