network firewall (quick question)

Hello, ok here goes. I was wondering if having firewall on the host computer of my computer network would protect all of my computers.

heres my setup.

modem>Router>desktop(hardwired)>Desktop (Hardwired)>notebook(wireless)>notebook(wireless)

so if i have Comodo internet security installed on the first desktop, will that protect all my computers? or do i need the firewall installed on all of them? Thanks in advance!

You will need to install the firewall on each computer to be completely protected.
