-In this method, the DSL Modem/Router connects to the DSL ISP for you with your credentials preprogrammed into the device and it gives you a local IP address such as 192.168.1.0/24 be default.
-For home networks this is usually fine and saves you trouble but if you want to run a configuration of your own controlled by VyOS, this would mean a Double Firewall, a Double NAT, and double Router as both the DSL Modem/Router and the VyOS would act as firewalls, NATs, and Routers and if you try to do more then just browse Web Sites this will usually cause you trouble.
