Eu entendi. Foi sob o Clone do endereço MAC
To enable MAC Cloning, simply click the option under the tab itself. You will have the option of either "Get current PC MAC" or you can input one yourself. Get current PC MAC is primarily used when establishing a service with an ISP that requires it, such as Comcast. The other option of manually entering a MAC address can be used for many things such as linking two routers together, or "spoofing" to force your ISP to give you a new IP address.
