How to access a Raspberry Pi remotely (without pesky port forwarding)

Accessing a Raspberry Pi remotely without the need for port forwarding, static IPs, or VPNs can be achieved using ngrok, which creates an outbound connection from the Pi to the ngrok cloud over port 443, bypassing most firewalls. This method involves installing the ngrok agent on the Raspberry Pi, registering an authentication token, and starting a TCP tunnel to port 22 to enable SSH access. The connection is secured by using an addressable endpoint provided by ngrok, allowing users to SSH from any network by connecting to the forwarding address. To maintain a stable connection across reboots, users can reserve a TCP address and configure the ngrok agent to run as a background service. Security can be enhanced by enabling SSH key authentication, disabling password login, and applying IP restrictions. This approach scales well for managing multiple remote devices, offering centralized management and secure access for a fleet of deployed devices.
