Konfiguration der NSX NAT (EN)
Using NAT rules to redirect traffic
Last updated 26th November 2021
Objective
NAT stands for network address translation. It’s a way to map multiple addresses to a single one.
There are two types of NAT:
- DNAT stands for Destination NAT. It modifies the destination address and is used for inbound traffic.
- SNAT stands for Souce NAT. It modifies the source address and is used for outbound traffic.
This guide explains how to create NAT rules.
Requirements
- being an administrative contact of your Hosted Private Cloud infrastructure to receive login credentials
- a user account with access to vSphere as well as the specific rights for NSX (created in the OVHcloud Control Panel)
- a deployed NSX Edge Services Gateway
Instructions

In the vSphere interface menu, go to the Networking and Security dashboard.
On the left side, navigate to the NSX Edges section then click on the appliance you're setting up.
Go to the NAT tab.
