5-4 Netopia ISDN Router Reference Guide
NetBIOS
NetBIOS is a protocol that per forms tasks related to the Transpor t
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 ser vers.
IPX Spoofing
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 ser ver, the
ser ver 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 ser ver 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
ser ver 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 ISDN Router for IPX. The information you enter here
controls how the router routes IPX traffic. Consult your network
administrator to obtain the information you will need, before
changing any of the settings.
Changes made in this screen will only take effect after the Netopia
ISDN Router is reset.
