If you want to use these ethernet ports as routed ports like build-in ethernet ports, You have two options listed below:
HWIC-1FE 1-port 10/100 Routed Port HWIC
HWIC-2FE HWIC two routed port

If you are going to connect some PC or other devices, you can use switch ports like below:
HWIC-4ESWFour port 10/100 Ethernet switch interface card

You have only two slot in this router so choose carefully.
