The TCP Protocol and UDP Protocol can provide different services and every
service has its TCP port or UDP port number . For example , TELNET(23) , FTP(21),
SMTP(25) , POP3(110) , and so on . The Service function includes two parts : Pre-
defined and Custom .
The Pre-defined included the common used and pre-identified TCP service or UDP
service .This kind of service can not be modified and canceled . On the other hand , the
user can set the proper TCP and UDP port number in Custom Service function.. When
sets the Custom Service function , the Client port number range is 1024 to 65535, the
server port is 0 to 65535 .
In this chapter , we will introduce the three common use services , for example ,
Pre-defined , Custom and Group. The MIS engineer can define the Protocol and port
number in every network applied communication by the following steps . The client
port can transfer the data by using different server.
How to use the Service ?
In Service
Æ
Group , the MIS engineer can add the new group name. In the
Group function , the MIS engineer can simply many process when setting the policy .
For example, there are 10 different IP address to access 5 different services via the
server, for example, such as the HTTP , FTP , SMTP , POP3 and TELNET . If the
MIS engineer do not use the Group function , he has to set 50 policy (10x5=50) .
Actually the MIS engineer only need to apply these services to the service group with
one policy.
