tox-tunnel-ops

Encrypted P2P TCP tunneling for remote network access — a self-hosted VPN / ngrok / Tailscale alternative built on the Tox protocol (libsodium). No API keys, no accounts, no central servers, no port-forwarding. Solves NAT traversal, carrier-grade NAT, double NAT, intranet penetration (内网穿透), and remote machine access without router or firewall changes.

Use when: setting up remote SSH/RDP/MySQL/PostgreSQL/Redis/MongoDB access f
