Wireguard Client Help

Good afternoon, I have been reading about this here on the Forum for several days now and I can't figure out what I want to achieve and I have to translate all the topics because my default language is Spanish, and for this topic I am using Google, I need some help with something that I don't know how to do, my problem is the following, I manage to install a Wireguard client on my router and connect, everything is fine, what I can't achieve is that the traffic from one of the LANs, that is, my PC's and one of the Wi-Fi networks that the router distributes, comes out, my PC's IP and the Wi-Fi networks are given by my Internet Provider, what I want is to be able to redirect the traffic from the Wireguard client to that LAN or to the IP of my PC and to the computers, which are attached to one of the Wi-Fi networks, another question, can I create a virtual Wi-Fi network through which I connect and which comes out through the Wireguard client, while it doesn't come out through the standard Wi-Fi network... any question? help me it's useful...
