# Configuring NAT for Port Redirections with NSX

**Learn how to configure NAT to create port redirections with NSX.**

## Requirements

- Being an administrative contact of your [Hosted Private Cloud infrastructure](https://us.ovhcloud.com/hosted-private-cloud/vmware/) to receive login credentials.
- A user account with access to the [OVHcloud Control Panel](https://manager.us.ovhcloud.com/#/hub).
- Having **NSX** deployed with two segments configured in your NSX configuration, you can use our guide on [segment management in NSX](https://docs.us.ovhcloud.com/en/hosted-private-cloud/vmware/nsx-segment-management.md) for more information.

## Instructions

When you deploy your NSX solution, a SNAT rule is automatically created by OVHcloud, so you can go online from your segments.

We will add a redirection rule (DNAT) from the public virtual IP address on port 2222 in TCP to a virtual machine on LINUX on port 22 in TCP. In our example, we will use fictitious IP addresses.

In the NSX interface, go to the `Networking` tab.

- Select `NAT` in the **Network Services** section.
- Select `ovh-T0-gw | Tier-0` to the right of **Gateway**.
- Click `ADD NAT RULE`.

Fill in this information :

- **Name: **enter to internal SSH
- **Action:** Select `DNAT`.
- **Source IP:** Enter the IP address or range of addresses that can use this redirection.
- **Destination IP:** Public virtual IP address of NSX.
- **Destination PORT:** Listening port on public address such as `2222`.
- **Translated IP:** IP address of the virtual machine being redirected to.

Then click on the `three vertical dots` to the right of **Select Services**. Select `Create New`.

 

Enter `SSH22` under the **Name** column and click `Set` under the **Service Entry** column. Then click `SAVE`.

 

Click `ADD SERVICE ENTRY`.

Fill in these values :

- **Name** : Enter `SSH22`.
- **Service Type** : Select `TCP`.
- **Source Ports** : Write the number `22`.

Then click `APPLY`.

 

Click `SAVE`.

 

Click `SAVE` to confirm the creation of the redirection rule.

 

The rule is created and active.

## Conclusion

Having read this guide, you should be able to configure NAT to create port redirections with NSX by adding a redirection rule.
