Step 8: Configure Subnet Access

•Select a transport type from the Transport column’s pulldown menu. The available transports are:

Transport

Description

ALL

This selection designates all of the protocols displayed in the

 

table’s pull-down list, as described below.

TCP

Transmission Control Protocol (TCP) is a set of rules used with

 

Internet Protocol (IP) to send data as message units over the

 

Internet. While IP handles the actual delivery of data, TCP

 

keeps track of individual units of data called packets. Messages

 

are divided into packets for efficient routing through the Internet.

UDP

User Datagram Protocol (UDP) is mostly used for broadcasting

 

data over the Internet. Like TCP, UDP runs on top of Internet

 

Protocol (IP) networks. Unlike TCP/IP, UDP/IP provides very

 

few error recovery services and methods. UDP offers a way to

 

directly connect, and then send and receive datagrams over an

 

IP network.

ICMP

Internet Control Message Protocol (ICMP) is tightly integrated

 

with IP. ICMP messages, delivered in IP packets, are used for

 

out-of-band messages related to network operation. Because

 

ICMP uses IP, ICMP packet delivery is unreliable. Hosts cannot

 

count on receiving ICMP packets for a network problem.

AH

Authentication Header (AH) is one of the two key components of

 

IPsec (IP Security Protocol). The other key component is

 

Encapsulating Security Protocol (ESP), described below.

 

AH provides authentication, proving the packet sender really is

 

the sender, and the data really is the data sent. AH can be used

 

in transport mode, providing security between two end points.

 

Also, AH can be used in tunnel mode, providing security like that

 

of a Virtual Private Network (VPN).

ESP

Encapsulating Security Protocol (ESP) is one of the two key

 

components of IPsec (IP Security Protocol). The other key

 

component is Authentication Header (AH), described above.

 

ESP encrypts the payload of packets, and also provides

 

authentication services. ESP can be used in transport mode,

 

providing security between two end points. Also, ESP can be

 

used in tunnel mode, providing security like that of a Virtual

 

Private Network (VPN).

GRE

General Routing Encapsulation (GRE) supports VPNs across

 

the Internet. GRE is a mechanism for encapsulating network

 

layer protocols over any other network layer protocol. Such

 

encapsulation allows routing of IP packets between private IP

 

networks across an Internet that uses globally assigned IP

 

addresses.

•Specify port information for the protocol. If a protocol uses only one port, enter the same port number in the Start Port and End Port columns, or leave the End Port column blank. Otherwise, use both columns for an entry that has a range of ports.
