NSmartProxy is a reverse proxy system that enables external access to devices or applications behind NAT/firewalls without requiring public IPs or router configuration. It’s designed to work with desktop and server apps, and includes a centralized SmartNode server that helps initiate and maintain tunnel connections. This makes it ideal for remoteaccess to local services or self-hosted applications.
...Its documentation includes examples for bypassing firewall limitations, tunneling through FTP, using remote internet access, and routing through remote desktop file shares. File-Tunnel is best understood as a specialized connectivity workaround for controlled environments where file access exists but normal network routing does not.
