Depending on a single firewall isn't considered good form.
Each machine should be hardened too.  Otherwise your network is
crunchy on the outside and tender on the inside.

This matters less in simple home networks.  But it is still a good idea if 
some of your other devices have security you cannot trust (eg. smart 
phones with apps that have some chance of being evil).  Windows 10 and 
most Linux distros have some hardening on each node.  I don't know or 
trust printers.

I don't remember the details, but we know that an HP Printer in
Saddam's Iraq was secretly working for the NSA.
