Welcome to McAfee Firewall
How can I still be harassed, even with McAfee Firewall?
Many people use McAfee Firewall (and PC FIREWALL) to block the "nukes"
that cause their IRC connections to be broken (shown in Figure 1-1). While
McAfee Firewall blocks the nukes, there are other ways that attackers can still
cause the connections to be broken:
• Server-side nuking. This is when the "nukes" are sent to the IRC server, not
to your computer, telling the server that you can no longer be reached. To
prevent this, the IRC server needs a firewall.
• Flood blocking a TCP connection. If a flood of packets is sent to you from
a higher speed connection, McAfee Firewall or ConSeal PC FIREWALL can
stop the packets, but the flood takes up all your bandwidth. Your system
does not get a chance to send anything. Dial-up users are particularly
vulnerable since they have the lowest speed connections.
