Personal firewall advantages

Freshness Warning

Another thing a software firewall can do that a NAT router cannot is protect computers on your network from the other computers on your network.

If one of your computers gets compromised or infected, or if a user on your network decides to be malicious, a NAT router won’t help you one bit. Traffic between computers on your network doesn’t pass through NAT, so a worm on one computer can infect all the other computers. A hacker who gains access to you network can then attack any machine on your network. If you have a wireless access point on your network, anyone connecting to it is immediately behind your NAT router and can connect to your other computers.

A software firewall like ZoneAlarm, Outpost, or Norton Personal Firewall can prevent such intrusions from your own network.

I have been looking at your web site but I didn't find some information. I wonder if you could help me about some ADVANTAGES AND DISADVANTAGES OF FIREWALLS and also WHO NEED FIREWALLS. I will be greatfull if you help me with these two questions. Thanks. Marta
