# Configure the LAN interface of an Edge Device

*Learn to configure the LAN Interface of a Tulip Edge Device.*

You can now configure the LAN interface of a Tulip Edge Device to act as an Upstream connection. By default, the LAN port will remain in the Downstream configuration.

Note that there are limitations to using the upstream LAN Interface such as:

- Cannot be used to communicate with the Internet, use the wired WAN interface or Wifi for this capability
- No DHCP—you must configure a static network connection for the LAN interface

## Switching to An Upstream Configuration

Setting the LAN interface to an upstream configuration is very similar to setting the Wired Interface to a Manual configuration. You will need to know the following information about the LAN network:

- Edge Device’s IP Address
- Subnet or Netmask e.g. 255.255.255.0
- Gateway or Router IP Address
- Any DNS Server Addresses

          WARNING

          

You should not connect the LAN interface prior to setting the upstream configuration to prevent network interference.

To set up the LAN interface to an upstream configuration, follow the steps below.

1. On the Device Portal, expand the LAN network configuration.
2. Select **Upstream** from the Configuration drop-down menu.
3. Enter the above information and hit **Save**.
4. Connect the LAN interface to the network.

## Switching to A Downstream Configuration

Switching back to the default Downstream configuration is very straightforward.

1. On the Device Portal, expand the LAN network configuration.
2. Select **Downstream** from the Configuration drop-down menu. All the default values will be automatically populated.
3. Hit **Save**.

**Edge Device**

**Edge Devices** are any hardware intended to connect physical things to the cloud. This can include entirely mechanical devices, older machines without network functionality, PLCs, and more.

Tulip sells the **Edge IO** and **Edge MC** that interface directly into **Triggers** in a breeze, but Tulip can also support other Edge Devices.
