# VPN Setup for Ubuntu/Linux

This source provides a technical guide for configuring VPN access to the Universität Greifswald network on Linux systems, specifically using Ubuntu (Xubuntu/XFCE) as the primary example.

## Key Technical Requirements
- **Software**: Requires `network-manager-openvpn-gnome` and `network-manager-openvpn`.
- **Authentication**: Uses "Password with Certificates (TLS)" which requires:
    - URZ account username and password.
    - A `.p12` certificate file (containing the user certificate and private key).
    - The password associated with the `.p12` file.
- **Routing**: Recommends enabling "Use this connection only for resources on its network" in IPv4 settings to implement split-tunneling.

## Configuration Workflow
1. **Installation**: Install the necessary Network Manager OpenVPN plugins.
2. **Cleanup**: Remove any existing VPN profiles to avoid conflicts.
3. **Import**: Import the university-provided profile file.
4. **Authentication Setup**: Configure the TLS settings by linking the `.p12` file for both the user certificate and the private key.
5. **Routing Configuration**: Set the connection to only route traffic destined for university resources through the VPN.
6. **Execution**: Connect/disconnect via the system tray network icon.
