Creating network objects
When you add a new host, a window similar to the following appears:
This window is used to define information about a host. (To create a different
network object, change the Type field.) Each host you define becomes a
network object that can be used in a rule.
Note: In IP Filter rules, the localhost network object is supported, but DNSresolvable
host names should be avoided. DNS-resolvable host names become
inoperative during any periods when the appropriate DNS server is unavailable or
unreachable.
1 In the Name field, type a name of the host. Valid values include
alphanumeric characters, periods (.), dashes(-), and underscores (_), and
spaces ( ). However, the first and last character of the name must be
alphanumeric. The name cannot exceed 100 characters.
This field cannot be edited if you are modifying an existing host.
2 [Optional] In the Description field, enter any useful information about this
host.
3 In the Host field, enter the hostname for this host object (for example,
mail.example.com).
4 In the DNS drop-down list, determine whether this host will use DNS:
• DNS—Select this option to perform normal DNS look-ups.
• No DNS—Select this option if you do not want to perform DNS lookups
for this host.
