To display NAT rules for a VM:

1. Go to Virtual datacenters → select VM → go to VM control panel → select NAT

   Image Added

To manage or display NAT rules for a VM:

1. Go to Virtual datacenters → edit VM → Networks → NAT

Create a NAT rule for DNAT

Create a NAT rule for SNAT

includeTo enable VMs outside your VDC to connect to a VM with a private IP address, after you obtain a NAT IP, create a destination NAT rule, which is also called a DNAT rule. 

To create a DNAT rule:

1. Go to Virtual datacenters → Virtual appliances → edit VM

2. If your VM does not yet have an IP, go to Network → NICs and add a private IP

3. Go to Network → DNAT

4. Click the + add button on the top right-hand side of the tab

5. Enter the details of the DNAT rule

   Image Added

   1. For the Original (NAT IP), select the IP address to receive external connections

   2. Select the Protocol for the connection, which can include TCP, UDP, any, and ICMP

   3. For the Translated IP, select the private IP that is attached to the VM

   4. Optionally, select the checkbox to Use all ports OR
      Enter the Original port for external connections. You cannot use an Original port for a NAT IP in more than one NAT rule.
      The platform will display the ports that are already used in other rules for the selected NAT IP.
      AND for the Translated port, enter the port on the VM

6. Click Add

7. Save the VM

Create a NAT rule for SNAT

Create To send outgoing traffic through a NAT IP that is not the default one, add an additional SNAT rule for SNATwith these steps:

To create an SNAT rule:

1. Go to Virtual datacenters → Virtual appliances → edit VM

2. If your VM does not yet have an IP, go to Network → NICs and add a private IP

3. Go to Network → SNAT

4. Click the + add button on the top right-hand side of the tab

5. Enter the addresses of the SNAT rule

   Image Added

   1. For the Original IP, select the IP that is attached to the VM

   2. For the Translated (NAT IP), select the IP address to display for outgoing connections

6. Click Add

7. Save the VM

Use a NAT IP for a load balancer

1. Use

1. the virtual datacenter's NAT IP address or obtain an additional NAT IP address. See Obtain an additional NAT IP address for a virtual datacenter

2. Create the load balancer and select the NAT IP

Image Added

The platform will automatically create a NAT rule to match the port mappings of the routing rule of the load balancer.

Obtain an additional NAT IP for your virtual datacenter

To obtain an additional NAT IP address for a virtual datacenterObtain an additional NAT IP address for a virtual datacenter:

1. Go to Virtual datacenters → Network → NAT

2. Click the + add button on the top right-hand side of the screen

3. Select the NAT network and click Accept

The platform will reserve an IP address and allocate it to your virtual datacenter.

Image Added

You can then use the NAT IP address as the public IP address for a load balancer or to provide access to a private IP address.

Limit NAT IP bandwidth for a VDC

When you create a virtual datacenter, the new "natbandwidthlimit" attribute is present but you must edit the virtual datacenter to enable it in the platform and in the NSX. 

Image Added

To edit the bandwidth limit and apply it in the NSX:

1. Select the virtual datacenter and go to Network → QoS

2. Click the pencil edit button 

   1. To enable the bandwidth limit in a specific direction, select the Enabled checkbox for that direction

   2. Set QoS values for your virtual datacenter. Be sure to allow enough bandwidth to share between all the NAT IPs in the virtual datacenter.

Image Added

To register changes that were made outside the platform, save existing NAT bandwidth values. In the API, to register changes, send a POST request with the existing values.
