This page describes how to create NAT rules for virtual datacenters. For details of how to configure NAT networks in infrastructure, see Manage NAT |
Display NAT rules
When the Network Address Translation (NAT) integration is available in your environment, to display NAT IPs and NAT rules:
Go to Virtual datacenters and select virtual datacenter
Go to Network → NAT
To display NAT rules for a VM:
Go to Virtual datacenters
Select the VM
Go to VM control panel → NAT
To manage or display NAT rules for a VM:
Go to Virtual datacenters
Edit a VM
Go to Networks → NAT
...
Create a NAT rule for DNAT
To 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:
Go to myCloud → Virtual datacenters → Virtual appliances
Edit your VM
If your VM does not yet have an IP, go to Network → NICs and add a private IP
Go to Network → DNAT
Click the + add button on the top right-hand side of the tab
Enter the details of the DNAT rule
For the Original (NAT IP), select the IP address to receive external connections
Select the Protocol for the connection, which can include TCP, UDP, any, and ICMP
For the Translated IP, select the private IP that is attached to the VM
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
Click Add
Save the VM
...
Create a NAT rule for SNAT
To send outgoing traffic through a NAT IP that is not the default one, add an additional SNAT rule with these steps:
To create an SNAT rule:
Go to Virtual datacenters → Virtual appliances
Edit your VM
If your VM does not yet have an IP, go to Network → NICs and add a private IP
Go to Network → SNAT
Click the + add button on the top right-hand side of the tab
Enter the addresses of the SNAT rule
For the Original IP, select the IP that is attached to the VM
For the Translated (NAT IP), select the IP address to display for outgoing connections
Click Add
Save the VM
...
Use a NAT IP for a load balancer
Insert excerpt
Use 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
Create the load balancer
...
and select the NAT IP
...
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
In addition to the NAT IP address assigned to the virtual datacenter, you can obtain NAT IP addresses for creating additional NAT rules.
To obtain an additional NAT IP address:
Go to Virtual datacenters → Network → NAT
Click the + add button on the top right-hand side of the screen
Select the NAT network and click Accept
The platform will reserve an IP address and allocate it to your virtual datacenter.
...
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.
