# Configure network interfaces

You can configure network settings from the **System Settings** tab on the server information page:

1. Go to the **Servers** view.
2. Click the **Details** `View` button to open the server information.
3. Go to the **System Settings** tab.

> **Warning:** Changes to network interface configuration can result in the device becoming unreachable.

## Set the hostname

1. Enter the new hostname in the **Hostname** field.
2. Click **Save** at the bottom of the page.

## Set IP addresses, subnet masks, gateway address, DHCP, and firewall zone

1. Go to the **Network devices** section on the **System Settings** page.
2. Click the **Edit** `Edit` button next to an interface to open its settings.
3. Enable or disable **DHCP**. When DHCP is enabled, the interface IP address and DNS servers are allocated automatically. DHCP-allocated values cannot be edited and are shown for reference only.
4. If DHCP is disabled, enter the IP address and subnet mask in the **Addresses** field using CIDR notation.
5. Optionally, enter the default gateway in the **Gateway** field.
6. Optionally, enter a value in the **Gateway metric** field. Usually this is left blank.
7. Optionally, set the firewall zone in the **Firewall zone** field. Valid values are **control**, **data**, or **control & data (public)**.
8. Click **Confirm**, then click **Save** at the bottom of the page.

> **Warning:** While you can configure multiple default gateways, this can cause routing issues and should be done with caution. If you define multiple gateways, ensure the **Control** interface has the lowest gateway metric. In most cases, adding a static route is the recommended way to achieve the desired routing.

## Configure static routes

> **Info:** Configuring static routes and gateway metric is possible in Beam 1.9 and later.

You can add static routes to an interface to direct traffic for specific subnets through a particular gateway. This is often a better alternative to configuring multiple default gateways.

1. In the **Network devices** section, click the **Edit** `Edit` button for the interface you want to configure.
2. In the **Edit Network Device** dialog, in the **Static routes** section:
   - To **add** a route, click **+ Add route**. Enter the **Destination (CIDR)** and **Gateway**, then click **Add Route**.
   - To **edit** a route, click the **Edit** `Edit` button next to it.
   - To **delete** a route, click the **Delete** `Delete` button next to it.
3. Click **Confirm** in the **Edit Network Device** dialog.
4. Click **Save** at the bottom of the **System Settings** page to apply the changes.

## Set DNS addresses

1. Go to the **DNS** section on the **System Settings** page.
2. Click the **Edit** `Edit` button next to an interface to open its DNS settings.
3. If DHCP is disabled, add at least one DNS server in the **Addresses** field using CIDR notation. DNS servers allocated by DHCP cannot be edited and are shown for reference only.
4. Click **Confirm**, then click **Save** at the bottom of the page.

## Set IGMP version

1. Go to the **IGMP mode** section on the **System Settings** page.
2. From the drop-down, select **Automatic v2/v3** or **Force v2**.
3. Click **Save** at the bottom of the page.

## Set time synchronization

See [Configure System Clock](/beam/system-admin/network/system-clock).

## Configure bonded interfaces

To configure active-backup bonded interfaces for redundancy from the command line, see [Configure Bonded Network Interfaces](/beam/system-admin/network/bonded-interfaces).
