UCO VPN Configuration

1
Install OpenVPN client
Choose your platform:
OpenVPN Community Edition (Windows, Linux, BSD) • Tunnelblick (macOS)
2
Download configuration files
uco-ca.crt — CA certificate (valid 2026-2036)
uco.ovpn — VPN connection profile
3
Connect to VPN
Use your UCO credentials when prompted

📅 OpenVPN config: 2019.10.10 (negotiated cipher) • 🔐 CA certificate: 2026.03 – 2036.03

Tunnelblick users: Tunnelblick must have DNS set to 3.0b10 behaviour or else external addresses will not be resolved.
NetworkManager users: NetworkManager must have dnsmasq disabled or else external addresses will not be resolved.
Windows users: Please run OpenVPN GUI and copy both the certificate and config files to your config directory (OpenVPN GUI will tell you the path). Connect using the OpenVPN GUI icon in the taskbar.

Alternative Method: All-in-One Configuration

Alternative Approach: This method embeds the CA certificate directly into the OpenVPN configuration file and uses a separate authentication file for credentials. This eliminates the need for a separate uco-ca.crt file and creates a more portable setup.
