Display NAT rules
When the Network Address Translation (NAT) integration is available in your environment, the NAT tab will display the NAT IPs and NAT rules for your virtual datacenters. From here you can manage NAT IPs and within the VM you can manage NAT rules.
Create a virtual datacenter with NAT
To create a virtual datacenter with NAT, create a virtual datacenter as usual, and the platform will automatically add a NAT IP and create an SNAT rule for all outgoing traffic. Then you can also create DNAT rules to associate a private IP attached to VM with a NAT IP, and an additional SNAT rule for that NAT IP.
Use a NAT IP for a load balancer
You can use a NAT IP as a public IP address for load balancers, and the platform will automatically create a NAT rule to match the load balancer routing rule port mappings.
Obtain an additional NAT IP
In addition to the NAT IP assigned to the virtual datacenter, you can obtain NAT IPs for creating additional NAT rules.
To obtain a NAT IP
- 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 and allocate it to your virtual datacenter.
You can then use the NAT IP as the public IP address for a load balancer or to provide access to a private IP address.
Create NAT rules
After you obtain a NAT IP, you can create a destination NAT rule for a private IP address on a VM.
To create a NAT 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 → NATs
- Click the + button on the top right-hand side of the tab
- Enter the details of the NAT rule, which by default will be a DNAT rule
- To create an additional SNAT rule for traffic from the private IP to the outside network through the NAT IP, select the SNAT checkbox
- Click Add
- Save the VM
Modify and delete NAT rules
From the NATs tab you can also select a NAT rule to edit or delete it.
