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 datacenter.
NAT IPs can be associated with private IPs attached to VMs using NAT rules. They can also be used 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 a NAT IP and configure SNAT for your VDC
When you obtain the first NAT IP, the platform will create a default SNAT rule for outgoing traffic from the virtual datacenter through this IP.
To obtain a NAT IP, click
- 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. If this is the first IP, the platform will create a default SNAT rule for outgoing traffic from the virtual datacenter.
The NAT IPs can also be used as a public IP address for load balancers, with a NAT rule to match the load balancer routing rule port mappings.
To manage NAT rules, go
Create NAT rules
After you obtain a NAT IP, you can create a 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
...
Enter the details of the NAT rule and click Add. Then save the VM.
...
- 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.
