A simple router has Network Address Translation (NAT) routing only.
This enables shared access to your broadband connection but no
incoming protection. A secure true Firewall uses Stateful Packet
Inspection (SPI) and Intrusion Detection features, Denial of Service
(DoS) attack protection etc. that keeps the bad guys from getting
in. The Netgear firewall I use makes my network invisible to anyone
seeking to find an open port entry.
