the service should not be available to
anyone (
Prohibit all
), available to everyone
(

) or only available to some (Permit
some). If you set

also specify the computer (under Comput-

Computer If the setting
Permit some
is selected
under
Method
, the relevant computers can
be specified here. The computers can be
entered with their IP addresses or host
names separated by commas. If a host
name is used, the system checks upon
closing or saving of the dialog whether
the host name can be translated into an
IP address. If this is not the case, an error
message is displayed and the dialog does
not terminate. If a valid host name is speci-
fied, this host name is translated into an
IP address each time the control is start-
ed. If a computer that was entered with its
name changes its IP address, you may have
to restart the control or formally change
the firewall configuration to ensure that the
control uses the new IP address for a host
name in the firewall.
