The expected behavior of the PRP protocol is based on two physical network adapters, one connected to network A and the other one connected to network B. However, this service may start and work temporarily with a single network adapter, as long as it was correctly configured at least once. The configuration of these real network adapters must respect the following rules:

•They cannot have an IP address enabled, as well as other network protocols

•They must have the same MAC (Media Access Control) address

To perform this configuration, execute the next procedures.

1.On the Start menu, open Control Panel and select Network Connections.

2.Right-click the Ethernet adapter that receives network A and select the Properties option.

3.On the properties window, disable all network protocols, including the Internet Protocol Version4 (IPv4) option, on the This connection uses the following items list, leave enabled only the Npcap Packet Driver option, and click OK to save these changes.

4.Open again the properties window of this adapter and click Configure.

5.Select the Advanced tab, click Network Address on the Property list, and define a MAC address in the Value option. This value must have a format of 12 hexadecimal digits, such as "02004C4F4F52".

6.Repeat these procedures for the adapter that receives network B.
