No. You _can_ be restrictive at the firewall; but most people in your
situation would probably have a rule which says, in effect, "all packets
generated on my local subnet are allowed out, and responses to
connections initiated from the local subnet are allowed in." If you
did want to be restrictive you could list individual machines instead
of the subnet.

And maybe your wallet. I'd steer clear. Why pay for features you don't
need? There are certainly fine, cheap hubs which don't do firewalling,
and I expect that your ISP provides all you need to get from their
service to the firewall.
