==== LaCie 5big NAS Pro Ethernet ports =====

{{:products:nas-pro:screenshots:dashboard:ss_db_network_05.jpg?350|}} \\ 

Icons representing the two LAN ports on the //Connections// tab indicate connection to the network:
  * Connected: **a**
  * Not connected: **b**

==== Port aggregation: multiple networks, load balancing, and fault tolerance ====
The LaCie 5big NAS Pro is equipped with two LAN ports for enhanced network performance. Review the instructions below to learn how to configure the LaCie 5big NAS Pro LAN ports for your network. \\ 

++++ Two networks: Bridge the data on your LaCie 5big NAS Pro |
The LaCie 5big NAS Pro can be shared by two separate networks.
  - Connect LAN 1 to the first network switch and LAN 2 to the second network switch.
  - Go to **Dashboard > Network** and choose the **Connections** tab.
  - If one or both LANs are not active, select the configuration icon to choose **Enable**. \\ {{:products:nas-pro:screenshots:dashboard:ss_db_network_06.jpg?500|}} \\ 
  - Once the LAN is enabled, it can receive a DHCP address from the router. Each LAN should have separate addresses to reflect connection to two separate networks. In the screenshot below, the subnets of the IP addresses (//5// for LAN 1 and //1// for LAN 2) demonstrate that each LAN is connected to its own network. \\ {{:products:nas-pro:screenshots:dashboard:ss_db_network_07.jpg?500|}} 

<note>**IP Addressing:** You can manually configure the IP addresses for the LAN connections by selecting their respective configuration icons (pencil) and choosing **Edit**.</note>

++++ Load balancing: enhanced speed |
Configure both Ethernet ports to act together for speeds up to 1.5 times faster than a single LAN connection. Additionally, you receive added security should one of the Ethernet cables or ports fail. \\ \\ 

Before following the directions below, make certain that your switch or router supports link aggregation:
  - Connect LAN 1 and LAN 2 to the same switch or router.
  - Go to **Dashboard > Network** and choose the **Connections** tab.
  - If one LAN is listed as inactive:
    * Confirm that it is securely connected to the device and to your router.
    * Select its configuration icon (pencil) to choose **Enable**. \\ {{:products:nas-pro:screenshots:dashboard:ss_db_network_06.jpg?500|}} \\ 
  - With both LANs enabled, choose **Link**. \\ {{:products:nas-pro:screenshots:dashboard:ss_db_network_08.jpg?500|}} \\  
  - Select **Load balancing** then choose **Next**. \\ {{:products:nas-pro:screenshots:dashboard:ss_db_network_09.jpg?500|}} \\ 
  - Check the boxes next to each LAN port then choose **Next**. \\ {{:products:nas-pro:screenshots:dashboard:ss_db_network_10.jpg?500|}} \\ 
  - You can name the LAN bonding as well as select how the paired Ethernet ports will receive a unified IP address (DHCP or Manual configuration). If you select //Manual configuration//, the IP address must be consistent with the values of your network. Choose **Finish** to complete the bonding. \\ [{{:products:nas-pro:screenshots:dashboard:ss_db_network_11a.jpg?500| \\ **//DHCP IP addressing//**}}] \\ \\ [{{:products:nas-pro:screenshots:dashboard:ss_db_network_11b.jpg?500| \\ **//Manual/Static IP addressing//**}}] \\ \\ 
  - The two LAN ports are now listed as one. \\ {{:products:nas-pro:screenshots:dashboard:ss_db_network_12.jpg?500|}} \\ 

**Break the LAN bond:** If you no longer wish to link the two Ethernet ports, follow the steps below.
  - Choose on the configuration icon (pencil) to select **Remove link**. \\ {{:products:nas-pro:screenshots:dashboard:ss_db_network_13.jpg?500|}} \\ 
  - Choose **Continue** at the prompt.
  - Removing the link may disable the secondary LAN interface. To reconnect the interface to the network, select the configuration icon for the secondary LAN to choose **Enable**.

++++ Fault tolerance: failover protection |
Configure fault tolerance to keep your LaCie 5big NAS Pro connected to the network even if one Ethernet port or cable fails. Before following the directions below, make certain that your network switch or router supports link aggregation. \\ \\ 
  - Connect LAN 1 and LAN 2 to the same network switch or router.
  - Go to **Dashboard > Network** and choose the **Connections** tab.
  - If one LAN is not active, select its configuration icon (pencil) to choose **Enable**. \\ {{:products:nas-pro:screenshots:dashboard:ss_db_network_06.jpg?500|}} \\ 
  - With both LANs enabled, choose **Link**. \\ {{:products:nas-pro:screenshots:dashboard:ss_db_network_08.jpg?500|}} \\ 
  - Select **Fault tolerance** then choose **Next**. \\ {{:products:nas-pro:screenshots:dashboard:ss_db_network_15.jpg?500|}} \\ 
  - Check the boxes next to each LAN port then choose **Next**. \\ {{:products:nas-pro:screenshots:dashboard:ss_db_network_16.jpg?500|}} \\ 
  - Fault tolerance will switch to the secondary LAN if it cannot detect the primary LAN (see [[network#lan-priority:-primary-lan-interface|LAN Priority: Primary LAN Interface]]). Choose the the fault detection for the bond, physical (e.g. a bad Ethernet cable) or logical (e.g. contact with another IP address). For logical fault tolerance, enter the IP address that the LaCie 5big NAS Pro will ping to confirm the stability of the primary LAN and the frequency. The IP address should be for a separate server, a computer on the network, or another device that can manage the task. Choose **Next**. \\ {{:products:nas-pro:screenshots:dashboard:ss_db_network_17.jpg?500|}} \\ 
  - You can name the fault tolerance configuration as well as select how the Ethernet ports will receive a unified IP address (DHCP or Manual configuration). If you select //Manual configuration//, the IP address must be consistent with the values of your network. Choose **Finish** to complete the bonding. \\ {{:products:nas-pro:screenshots:dashboard:ss_db_network_18.jpg?500|}} \\ 
  - The two LAN ports are now listed as one. \\ {{:products:nas-pro:screenshots:dashboard:ss_db_network_19.jpg?500|}} \\ 

**Break the Fault Tolerance:** If you no longer wish to keep Fault Tolerance, follow the steps below.
  - Select the configuration icon (pencil) to choose **Remove link**.
  - Choose **Continue** at the prompt.
  - Removing the link may disable the secondary LAN interface. To reconnect the interface to the network, select the configuration icon for the secondary LAN to choose **Enable**.
++++

<note>**Note on failover for bonding versus fault tolerance:** Both bonding and fault tolerance can save you from losing productivity in the event that a single LAN fails (e.g. port, router port, cable, etc.). While the bonded ports can adapt to the loss of one Ethernet signal, it can take a few minutes for the NAS to switch to single LAN mode. Fault tolerance will make the switch instantly, allowing for uninterrupted communication with the NAS.</note>

=== LAN priority: primary LAN interface ===
The primary Ethernet port is marked by a star next to the LAN number. In the example below, LAN 1 is the primary Ethernet port. \\ {{:products:nas-pro:screenshots:dashboard:ss_db_network_36.jpg?500|}} \\ 

The primary Ethernet port:
  * Carries the data when the LaCie 5big NAS Pro is configured in Fault Tolerance
  * Acts as the gateway to the internet when the LaCie 5big NAS Pro is connected to two separate networks

<note>**LAN interface and LaCie Network Assistant:** LAN Port 1 must be enabled to use LaCie Network Assistant.</note>

You can change the priority order by reassigning the role of primary port.
  - Select the configuration icon (pencil) for the port you wish to assign as the primary. \\ {{:products:nas-pro:screenshots:dashboard:ss_db_network_37.jpg?500|}} \\ \\ 
  - Choose **Define as primary**.
  - The star icon will move to the port to reflect the change. \\ {{:products:nas-pro:screenshots:dashboard:ss_db_network_38.jpg?500|}}

===== Proxy tab =====

{{:products:nas-pro:screenshots:dashboard:ss_db_network_39.jpg?500|}}

A proxy server may be used to connect compatible network devices to the internet. If necessary, your LaCie NAS can be configured to use a proxy server. First, activate the feature by selecting the **Proxy server** option from the drop-down menu, then fill in the proxy server address, port, and optional authentication information. Choose **Apply** for your changes to take affect.

===== Remote access tab =====

See [[..:remote-access:mynas|]].

~~pgbreak~~

===== Port forwarding tab =====

{{:products:nas-pro:screenshots:dashboard:ss_db_network_41.jpg?500|}}

Use this page to manage your LaCie NAS's port forwarding. \\ \\ 

To access the internet, file and application services (e.g. HTTP, HTTPS, remote access (see [[..:remote-access:mynas|]]), download machine, and more) use port numbers on the LaCie NAS and the network router. As seen in the screenshot above, automatic port forwarding is turned on by default and the port numbers are the same for both the //NAS port// and //Router port// columns. \\ \\  

In most instances, automatic port forwarding should help you access services on the NAS. However, enterprise-level network security or port availability on your router can prevent access to ports. Therefore, it may be necessary to change the router port numbers manually for services. Before adjusting numbers in this tab, confirm that the ports you wish to use are available on your router. For example, if you intend to change download machine to router port number 8800, you must make certain that port 8800 is available on your router. Additionally, your router must be compatible with UPnP-IGD/NAT-PMP protocols. See your router's user manual for details. \\ \\ 

To change the router port for a service on the NAS, choose its value in the **Router port** column. \\ {{:products:nas-pro:screenshots:dashboard:ss_db_network_40.jpg?500|}} \\ \\ 

To disable port forwarding for a service, select its configuration icon (pencil) and then choose **Disable**.

<note>**Note on Services in the Port Forwarding tab:** Download machine and other services will appear in this tab once they have been enabled.</note>
