# 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** button to open the server information.
3. Go to the **System Settings** tab.

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** 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.

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

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** 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** button next to it.
   - To **delete** a route, click the **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** 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](https://docs.mediakind.com/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](https://docs.mediakind.com/beam/system-admin/network/bonded-interfaces).
