Display NAT rules
Create a virtual datacenter with NAT
Use a NAT IP for a load balancer
You can use a NAT IP as a public IP address for load balancing.
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
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 DNAT rules
To enable VMs outside your VDC to connect to a VM with a private IP address, after you obtain a NAT IP, you can create a destination NAT rule.
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 → DNAT
- Click the + button on the top right-hand side of the tab
Enter the details of the DNAT rule
Field Description Original (NAT IP) Select the IP address for external connections Protocol Select the protocol for the connection, which can include TCP, UDP, any, ICMP Translated (private iP) Select the private IP that is attached to the VM Use all ports Mark this checkbox to create a NAT rule for all ports Original port Enter the port for external connections. You cannot use the Original port for the 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. Translated port Enter the port on the VM - Click Add
- Save the VM
Create SNAT rules
To send outgoing traffic through a NAT IP that is not the default one, you can add an additional SNAT rule on the SNAT tab.
Modify and delete NAT rules
From the NAT tabs you can also select a NAT rule to edit or delete it.
