Like most tutorials I've seen this lacks on the AllowedIPs part on the client's peer. First of all it creates routes on the client side and secondly you can configure this quite a lot by giving it a comma separated list of networks or giving it a route-all by using 0.0.0.0/0 Not that is configured on the client side, if you don't want the client to mess around in your server's network beyond certain IPs, then you need to add a firewall on the server.
