Dear Experts,

I have a newbie question about firewall, and hope you can explain to me.
Thanks beforehand.

My home network has three computers, and uses ADSL for Internet connection.
I just use a normal ADSL modem/router, and use 192.168.x.x addresses in LAN.
These addresses are non-routable, which means that other people cannot
access my computers from outside using these IP addresses. So, why should I
enable firewall in my modem/router settings?

Any reply is appreciated. Thanks!

Lei
