Raspberry Pi 4B (2GB) Router with OpenWRT

Purpose and Benefits

This custom router project was created with the primary goal of establishing a separate network dedicated to handling external SSH traffic. This setup offers several advantages:

• Enhanced Security: By segregating external SSH traffic from the main local network, you create an additional layer of security, minimizing potential risks associated with direct access to sensitive systems.

• Optimized Network Performance: Allocating a dedicated network for SSH traffic ensures that it doesn't compete with other activities on the main network, resulting in smoother, more reliable connections.

• Isolation of Services: The isolated network allows you to manage and monitor SSH connections separately, making it easier to identify and respond to any unusual activity.

• Flexibility and Control: This setup provides you with greater control over SSH access, allowing for specific configurations tailored to your needs.

Project Overview

This project showcases the creation of a custom router using a Raspberry Pi 4B with 2GB of RAM, running the powerful OpenWRT operating system. This setup leverages the Raspberry Pi's capabilities alongside OpenWRT's robust networking features. It makes use of a Cana Kit external WiFi adapter for broadcasting a WiFi signal. Additionally, the internal WiFi card of the Pi connects to the main router for internet access. For wired connections, a 5-port unmanaged TP-Link Ethernet switch is integrated. To regulate temperature, a fan is included within the custom case. The Pi router is securely mounted on top of the switch using Velcro. Furthermore, a Pico W is Velcroed to the top of the router, providing essential functionality.
