Hotel, campus, office and some national networks block VPNs on purpose. The RoTunneling VPN app is built to get through: it tests the network, finds a path that is allowed and connects you to our servers in Bucharest, with a Romanian IP and unlimited traffic.

Why other VPNs get blocked

Most VPN protocols have a recognisable signature: fixed ports, a distinctive handshake, traffic patterns that deep packet inspection (DPI) can spot. A network that wants to stop VPNs simply drops that traffic, or lets it through so slowly that it becomes useless.

How RoTunneling gets through

  • It looks like a browser. Every connection opens with the same TLS handshake as a current web browser, on port 443, the port every HTTPS site uses.
  • Six transport modes, chosen automatically. TCP with UDP acceleration for speed, then UDP, DNS and ICMP for networks that block more, and finally a cloud relay or WebSocket over a CDN for the strictest ones, where the connection looks entirely like an ordinary website.
  • Automatic discovery and retry. The app tests which ports and transports the network allows, remembers what works and switches to the next option on its own when a path stops working.
  • HTTP proxy support. On networks that only allow traffic through a proxy, the app connects through it, with optional authentication.

You do not have to choose anything: keep the server on Automatic and press Connect.

Security on hostile networks

  • TLS 1.3 with AES-256-GCM and a post-quantum key exchange (X25519MLKEM768).
  • A kill switch that blocks internet traffic if the VPN drops, so nothing leaks while the app reconnects.
  • Protected DNS that blocks malware, phishing and trackers.

Supported devices

The RoTunneling VPN app with all six transport modes runs on Windows 10 and 11, Linux (Debian, Ubuntu) and Android. On macOS, iOS and routers you can connect with OpenVPN (TCP 443) or L2TP/IPsec; on Windows, SSTP also runs over TCP 443. See the downloads page for every option.

Frequently asked questions

Will it work on my hotel, university or office network?

In most cases, yes: if the network lets you browse HTTPS sites, the app can usually connect through one of its transport modes. No method can promise to pass every block, so try it during your first days and write to [email protected] if it does not connect.

Is the connection slower in the stricter modes?

The app always tries the fastest mode first. The fallback modes for very strict networks favour getting through over raw speed, so they are used only when the faster modes are blocked.

Do I have to configure ports or protocols?

No. The app discovers what the network allows and picks the transport and port by itself. Advanced users can still adjust ports and transports in the Performance settings.
