specific host.

• A host name.

• Any IP address.

Mask

If you selected A specific IP address, either select the wildcard mask from this

list or enter a custom wildcard mask. A binary 0 in a wildcard mask means that

the corresponding bit in the packet’s IP address must match exactly. A binary 1 in

a wildcard mask means that the corresponding bit in the packet’s IP address need

not match.

Hostname

If you selected A host name in the Type field, enter the name of the host.

Description

You can enter a short description of the entry in this field. The description must

be fewer than 100 characters long.

Protocol and Service

Select the protocol and service, if applicable, that you want the entry to apply to.

The information that you provide differs from protocol to protocol. Click the

protocol to see what information you need to provide.

Available when either TCP or UDP is selected. Setting this field will cause the

router to filter on the source port in a packet. It is rarely necessary to set a source

port value for a TCP connection. If you are not sure you need to use this field,

leave it set to = any.

Destination Port

Available when either TCP or UDP is selected. Setting this field will cause the

router to filter on the destination port in a packet.
