At the Networking step of the wizard, select the network mode that will be used by the cloud gateway to communicate with Veeam backup servers on tenants’ side.
You can choose between two network modes: direct mode or NAT mode.
- If a cloud gateway has a direct network connection to Veeam backup servers on tenants’ side, select This server is connected directly to the internet. From the NIC list, select a network interface card on the cloud gateway that will be used to communicate with tenants’ Veeam backup servers.
- If a cloud gateway is located in the local network behind the NAT gateway:
- Select This server is located behind NAT.
- In the DNS name or IP address field, specify a DNS name or an external IP address of the NAT gateway.
- In the Internal port field, specify a port on the local network behind the NAT used for listening to connections from tenants. By default, port 6180 is used.
- On your NAT gateway, configure the port forwarding rule: from an incoming port (specified in the External port field at the previous step of the wizard) to the port on the local network used for listening to connections (specified at the Incoming port field at this step of the wizard). For example, if you use default port number values, you must configure the following port forwarding rule: from port 6180 to port 6180.

If you use an SSL certificate verified by a CA to establish a secure connection between Veeam Cloud Connect infrastructure components, it is recommended that you choose This server is located behind NAT network mode for all cloud gateways, including those that have direct network connection to the internet. To learn more, see Network Settings with Verified SSL Certifcates. |
Network Settings with Verified SSL Certificates
If you use a verified SSL certificate in your Veeam Cloud Connect infrastructure, it is recommended that you configure a cloud gateway in the following way:
- DNS names of all cloud gateways in Veeam Cloud Connect infrastructure must be associated with the verified SSL certificate.
- For all cloud gateways, specify the following network settings in the New Cloud Gateway wizard:
- Select This server is located behind NAT.
- In the DNS name or IP address field, specify an external DNS name of the cloud gateway (in case of direct connection) or a DNS name of the NAT gateway (if a cloud gateway is located behind the NAT gateway).
- In the Internal port field, specify a port used for listening to connections from tenants:
- If a cloud gateway has a direct connection to the internet, specify the same port that was specified in the External port field at the previous step of the wizard By default, port 6180 is used.
- If a cloud gateway is located in the local network behind the NAT gateway, specify the same port that is specified in the port forwarding rule on your NAT gateway.
