Deployment behind an NAT device

Successful deployment is not guaranteed if Acronis Snap Deploy 4 OS Deploy Server and the target machines are separated by a Network Address Translation (NAT) device. A typical router usually acts as an NAT device.

All machines behind an NAT device normally form a separate subnet and appear to the deployment server as having the same IP address. This may lead to problems when connecting to components of Acronis Snap Deploy 4 and when showing the deployment progress for each target machine.

To avoid these problems, we recommend installing Acronis Snap Deploy 4 OS Deploy Server in the same subnet as the target machines.

If installing the deployment server in that subnet is not possible, configure the NAT device as follows:

1. Set up port forwarding for the NAT device:
   • If Acronis Wake-on-LAN Proxy is installed in that subnet, forward the TCP and UDP ports 9876 to the machine with the Wake-on-LAN proxy.
   • If Acronis PXE Server is installed in that subnet, forward UDP ports 67, 68, and 69 to the machine with the PXE server.
2. When creating the deployment task, specify the IP address of the NAT device when asked about the address of the PXE server and/or of the Wake-on-LAN proxy.

Even after you configure the NAT device this way, you might still receive inconsistent information about the deployment progress for each machine.
