Hello Brennen,

You can use an Eero device as your router by connecting it directly to your cable modem, the Eero device will act just like any other router, and has the ability to port forward if needed and even configure your own private DNS. The only limitation is that the Eero has two ethernet ports, one will be used to connect the cable modem and then the other can be used to connect a computer or even a network switch to give you the ability to hardwire more than one device. You can take a look at some of the network configurations that are supported here.
