```{important}
Network connection and bridge equipment configuration must be performed by a qualified service engineer.
```

### Connection Permission

| Menu Path |
|-------------|
| {{ menu }} → {{ settings }} → System → Network → Connection permission |

Create rules that permit external connections.

ECDIS can operate as a standalone unit or as part of a bridge system (within the bridge's internal secure network). Implementing the requirements of IEC 61162-460, ECDIS allows external connections to the workstation from an external network directly.

```{caution}
Connections are only permitted to trusted external uncontrolled networks or to controlled networks.
```

Since the firewall blocks all connections by default, establishing a connection requires creating an individual connection rule that applies to a single source.

### Network Connection

| Menu Path |
|-------------|
| {{ menu }} → {{ settings }} → System → Network → Network connection |

Configuration of network connections — ECDIS network cards are configured here.

ECDIS can operate in two bridge networks simultaneously, providing redundant connections to the bridge system and sensors — primary and backup.

| **1** | **Network connections** | List of network connections. |
| **2** | **Add** | Add a new network connection. |
| **3** | **Delete** | Delete a network connection. |
| **4** | **Settings** | Configure a network connection. |

```{error}
Any operations with network settings: creation, configuration, deletion, or modification must be performed by a qualified user.

Making changes to the network configuration without proper qualifications may render the ECDIS inoperable.

| **13** | **Bonding interface** | List of network interfaces available for redundancy. |

```{error}
Network connection settings must be performed by a qualified user.

Making changes to the network configuration without proper qualifications may render the ECDIS inoperable.
```

1. Select the connection type
2. Configure the network connection in accordance with the bridge network architecture.
3. Save

```{tip}
ECDIS can operate simultaneously with multiple connections in different networks.
```

```{caution}
ECDIS does not support {doc}`**WiFi** </sections/general-information/manufacturer-declarations/index>` interfaces. When any **WiFi** device is connected, ECDIS will not recognize it and will not support further operation.
```

### IPv4 Configuration and Connection
1. Configure settings on the **IPv4** tab.
2. If the network has a DHCP server, select the **DHCP** connection method and press **Save**.
3. If the network uses static addressing, switch the mode to **Static** and configure: **Gateway**, **DNS**, **IP**, and subnet mask. Add a device IP address — press "+". The "−" button deletes the selected IP address from the list. Set the connection parameters in accordance with the local network settings and press **Save**.
4. After **saving**, the connection data will be updated.
5. Go to the **Network devices** tab and press **Connect** in the row of the new device.
6. Select the created connection from the drop-down list and press **Connect**.
7. If the connection is successful, the interface list will update to show ("<device> Connected").

### Network Devices
