Actually, if you have only a modem, you'll need a router to route traffic out. Your modem would connect to the WAN port on your router, and then your ethernet port would connect to the LAN side. You would configure NAT on the router so all of your hosts would be able to get on the internet.

If you have a broadband router, you'll need to have your ISP help you configuring their router that they sent you in bridging mode. Bridging allows all of the public traffic through their device and allows your Cisco router to handle all of it.

It is possible to connect a Router..Connect the Broadband modem to the router through ethernet port..then Lan will be connected to the router..Do a default route on the Router pointing towards the Broadband modem..
