If you have a NAT packet filtering FW router that meets the specs in the
link for *what does a Internet/network FW do?*, then you have one that
has a FW. If the router doesn't meet those specs, then you don't have
one and you just have a NAT router for home usage that is using some FW
like features but is doesn't meet the definition for a network FW.

The definition of NAT and that NAT router for home usage is what you
most likely have epecially true for most wireless NAT routers, even with
SPI.
