# Adding a new Tier-1 Gateway in NSX

## Objective

OVHcloud provides you with NSX with two gateways, a north-south gateway (ovh-T0-gw) and an east-west gateway (ovh-T1-gw). You can create additional east-west gateways.

**Learn how to add an east-west (Tier-1 Gateway) gateway to your NSX configuration.**

:::warning
OVHcloud provides services for which you are responsible, with regard to their configuration and management. It is therefore your responsibility to ensure that they work properly.

This guide is designed to assist you as much as possible with common tasks. However, we recommend contacting a [specialist provider](https://partner.ovhcloud.com/en-gb/directory/) if you experience any difficulties or doubts when it comes to managing, using or setting up a service on a server.

:::

## Requirements

- Being an administrative contact of your [Hosted Private Cloud infrastructure](https://www.ovhcloud.com/en-gb/enterprise/products/hosted-private-cloud/) to receive login credentials
- A user account with access to the <ManagerLink to="/">OVHcloud Control Panel</ManagerLink>
- Having **NSX** deployed.

:::warning
Through your NSX interface, you can create north-south gateways.
We strongly advise you not to do it because some options are not available and you will not be able to make such a gateway work correctly.

:::

For more information on NSX at OVHcloud, please refer to our [Getting started with NSX](/en/guides/hosted-private-cloud/powered-by-vmware/nsx-first-steps.md) guide.

## Instructions

We will add a new east-west gateway (Tier-1-Gateways) and link it to the north-south gateway provided by OVHcloud (ovh-T0-gw).

Next, we will create a segment and attach a virtual machine to it.

### Creation of the new east-west gateway

In the NSX interface, go to the `Networking
` tab and click on `Tier-1 Gateway
` on the left.
Then click on `ADD TIER-1 GATEWAY
`.
![Add tier1-gw 01](/images/hosted-private-cloud/powered-by-vmware/nsx-10-add-new-tier1-gateway/01-add-tier1-gw01.png)
Enter the name of your new gateway as `new-T1-gw
` below **Name**
 and fill in these parameters:
- **Linked Tier-0-Gateway** : Your north-south gateway <code className="action">ovh-T0-gw</code>.
- **Edge Cluster** : Your <code className="action">edgeXXX-X</code>.
- **Fail Over** : <code className="action">Non Preemptive</code>.
- **Edge Pool Allocation Size** : <code className="action">Routing</code>.

Then click the `Down Arrow
` to the left of **Route Advertisement**
.
![Add tier1-gw 02](/images/hosted-private-cloud/powered-by-vmware/nsx-10-add-new-tier1-gateway/01-add-tier1-gw02.png)
Select the `button
` to the right of **All Connected Segment & Service Ports**
 if you want to connect outside this gateway, then click `SAVE
`.
![Add tier1-gw 03](/images/hosted-private-cloud/powered-by-vmware/nsx-10-add-new-tier1-gateway/01-add-tier1-gw03.png)
Click `NO
`.
![Add tier1-gw 04](/images/hosted-private-cloud/powered-by-vmware/nsx-10-add-new-tier1-gateway/01-add-tier1-gw04.png)
Your new gateway is displayed and we can see it connected to your north-south gateway (ovh-T0-gw).

![Add tier1-gw 05](/images/hosted-private-cloud/powered-by-vmware/nsx-10-add-new-tier1-gateway/01-add-tier1-gw05.png)
Click `Network Topology
` in the vertical menu bar to the left to view your network topology and to display your new **new-T1-gw**
 gateway connected to **ovh-T0-gw**
.
![Add tier1-gw 06](/images/hosted-private-cloud/powered-by-vmware/nsx-10-add-new-tier1-gateway/01-add-tier1-gw06.png)
### Adding a segment on your new gateway

Go to `Segments
` on the left and click `ADD SEGMENT
`.
![02 Add Segment on new gateway 01](/images/hosted-private-cloud/powered-by-vmware/nsx-10-add-new-tier1-gateway/02-add-segment-on-new-gw01.png)
Fill in this information :

- **Name** : Name of your segment <code className="action">ov3-segment</code>.
- **Connected Gateway** : Your new gateway <code className="action">new-T1-gw</code>.
- **Transport Zone** : Your subnet `192.168.120.254/24`.

Click `SAVE
`.
![02 Add Segment on new gateway 02](/images/hosted-private-cloud/powered-by-vmware/nsx-10-add-new-tier1-gateway/02-add-segment-on-new-gw02.png)
Click `NO
`.
![02 Add Segment on new gateway 03](/images/hosted-private-cloud/powered-by-vmware/nsx-10-add-new-tier1-gateway/02-add-segment-on-new-gw03.png)
Your new segment is created and connected to your new **new-T1-gw** gateway.

![02 Add Segment on new gateway 03](/images/hosted-private-cloud/powered-by-vmware/nsx-10-add-new-tier1-gateway/02-add-segment-on-new-gw03.png)
### Displaying a complete configuration with a virtual machine on your segment.

The segment created is of type Overlay but it is possible to add a segment of type VLAN and connect it to your new gateway.

Use our guide on [segment management in NSX](/en/guides/hosted-private-cloud/powered-by-vmware/nsx-segment-management.md) to add a new virtual machine to your new segment.

Then click `Network Topology
`.
