Address settings are required to apply to network policies to be practical and
effective.
4.2 Service
Network services are provided through TCP and UDP protocols using
different port numbers, such as Telnet port 23, FTP port 21, SMTP port 25,
POP3 port 110, etc. MH-2300 provides TCP and UDP services by the two
following categories:
„ Pre-defined: The default TCP and UDP services, which are not
removable.
„ Custom: The user-definable TCP and UDP services, which allow the
configuration of associated service ports.
Under Policy Object > Service > Group, group the desired services together
and then apply it to a network policy so as to facilitate the management. For
example, to allow a user (a specific IP address) to access five different services
(HTTP, FTP, SMTP, POP3 and Telnet), it only takes a service group to achieve
the management that originally requires five separate policies.
