This article describes how to configure the 1 to Many NAT feature on your Datto Networking Appliance (DNA).
- Datto Networking Appliance (DNA)
The Datto Networking Appliance allows you the ability to configure port-forwards from multiple IP addresses so that you can accommodate many internal hosts. This allows more port-forwards than IP addresses.
2. Once on the Networks page, in the left-hand sidebar, click the Add button next to the Custom DNS option of your selected port. The following examples use WAN Port 2.
3. On the WAN Port card, configure the Static Address values for your environment.
4. Configure the WAN port's DNS settings.
5. Click Save Changes.
6. Click the Security tab, followed by 1 to Many NAT.
4. Click the Ingress IP for each address configured on the port that you want to create rules for. Then, click New Rule.
5. Configure your NAT rules as desired. The options are:
- Name: Specify a name for the NAT rule
- Incoming Port(s): Choose Single or Range from the dropdown, and specify the port range
- Protocol: Select TCP, UDP, or Both
- Destination IP: Specify the destination IP to forward the connection to.
- Port: Specify the port to forward the connection to.
6. You can create multiple rules per ingress IP, and specify up to 4 ingress IPs per port. When you are finished creating rules, click Save Changes. Your DNA will display a summary of your port configuration, as shown in Figure 6.
