TCP/IP 2

[mikestips]

On windows 2000 server is an advanced nic option that you can kind of configure you own firewall.
there are three portions: TCP, UDP, IP .
My question is if there is a port for tcp, upp, why is there an option for IP port

TCP and UDP operate at layer 4 of the OSI model, and use ports associated with numbers to connect. IP operates at layer three, and does not use port numbers. It is a simpler protocol, that operates at a simpler layer, and only utilizes logical addressing (IP addresses, IPX addresses), and does not use ports to connect.

IP is composed of tcp and udp. Ports are a TCP or UDP feature, IP refers to actually host addresses.
