NetBIOS

NetBIOS is a protocol that per forms tasks related to the Transport
and Session layers of the OSI model. It can operate over IPX, using
a special broadcast packet known as “IPX Packet type 20” to
communicate with IPX NetBIOS servers.

IPX Spoofing

Applicable only to ISDN

switched lines

The Netopia has several IPX features designed to restrict the traffic
on the ISDN link when the unit is not sending or receiving IPX data.
When the link is idle and a user is logged into a Novell server, the
server will send “keep alive” packets to ensure the user is still
there. If the link is idle, the “keep alive” packets will be sent back to
the server by the locally connected Netopia router as though they
came back from the user without bringing up the ISDN link.

Similarly, “SPX keep alive” packets are treated in this manner. IPX
RIP, and SAP messages will not be sent if the link is down. Together
these features enable the user to remain connected to a Novell
server or SPX peer without bringing up the ISDN link, except to send
and receive actual user data.

IPX setup

The IPX Setup screen is where you configure the Ethernet side of
the Netopia Router. The information you enter here controls how the
Router routes IPX traffic.

Consult your network administrator for the IPX setup information you
will need before changing any of the settings in this screen.
Changes made in this screen will take effect only after the Netopia
Router is reset.
