Are There Any Data Packets That Mcafee Firewall Cannot Stop; What Network Devices Does Mcafee Firewall Support; What Protocols Can Mcafee Firewall Filter - McAfee FIREWALL 2.1-GETTING STARTED Getting Started

Are there any data packets that McAfee Firewall cannot
stop?
Inbound Data: No.
As long as McAfee Firewall supports a network device and is running, it is
intercepting all incoming packets and will allow or block according to the way
you have it configured. If you choose to block everything, it will.
Outbound Data: Yes and no.
McAfee Firewall intercepts outbound data packets as they are passed to the
network device driver. All popular applications communicate this way. A
malicious program could communicate by other means, however.

What network devices does McAfee Firewall support?

McAfee Firewall supports Ethernet and Ethernet-like devices on Microsoft
Windows 95, 98 and NT 4.0 SP4 and SP5. This includes dial-up connections,
most cable and ISDN modems and most Ethernet cards. It does not support
Token Ring, FDDI, ATM, Frame Relay and other networks.

What protocols can McAfee Firewall filter?

McAfee Firewall can filter TCP/IP, UDP/IP, ICMP/IP and ARP. It intercepts
all protocols, but others, such as IPX, must be either allowed or blocked - no
filtering is done. The Internet uses the IP protocols. No others are sent. Also,
IP networks are the most common.
