228 Sniffer Portable Professional
You can filter by a specific IP or IPX port.
NOTE: If Hardware is selected as the Address Type in the Address
tab of the Define Filter dialog box, all fields in the Port tab of the
Define Filter dialog box are disabled. By default, IP is selected as
the Address Type when you open the Define Filter dialog box.
To filter by a specific port:
1 Select the Define Filter command from either the Monitor,
Capture, or Display menu (depending on the type of filter you

Address Type. If Hardware is the selected Address Type, all fields
of the Port tab are disabled.

those in your Address Book). The list is dependent on the Address
Type selected in the Address tab of the Define Filter dialog box. If
IP is selected, the list displays known IP ports. If IPX is selected,
the list displays known IPX ports.
NOTE: Filtering by TCP or UDP ports is not supported.
5 Enter a port number in the Port 1 or Port 2 field by dragging and
dropping a known port from the list above into the desired field.
You can also manually add ports by placing your cursor in the
appropriate field and typing.
You can enter multiple ports by separating entries with a
comma (for example, 23,25).
You can enter a range of ports by using a hyphen. For
example, you can specify ports 23, 24, 25, and 26 by entering
23-26 in the Port field.
