Creating a NAT rule for Edge Gateway

Introduction

Network Address Translation (NAT) allows the source or destination IP address to be changed to enable traffic through a router or gateway.

NAT rules can only be managed with a Virtual Data Center that is provisioned with an Edge Gateway. NAT rules will be applied to the Edge Gateway not the internal VDC network. The firewall needs to be opened for a NAT rule.

Prerequisites (applicable only for DNAT rules)

To use a custom port, you must create an Application Port Profile before creating a rule.

Application Port Profiles:

There are more than 400 applications are already available, built-in to an Edge Gateway.

Click on the Virtual Data Center where there is an Edge Gateway
Select Edges from the menu to the left
Select the Edge
Go to the section named Application Port Profiles, under Security, click New

Enter the application name and description. Select the protocol and enter the required port(s).
Click on Save
