[John Buchanan]

In my view, software firewalls are always necessary, wired or wireless, router with or without a hardware firewall.

Software firewalls are necessary even when you are behind a NAT router (with or without firewall in the router).

Surely the NAT and possible stateful inspection firewall of your router help to keep bad guys from breaking in. They don't protect when you have ports open nor does it protect you from the danger of other computers on your local network. Neither do NAT and router firewall keep an eye on outgoing traffic.

You need a decent firewall on your computer to monitor both incoming and outgoing traffic.
