NetBIOS

NetBIOS is a protocol that performs 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

The Netopia R2020 has several IPX features designed to restrict the trafﬁc on the dial-up 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 R2020 as though they came back from the user without bringing up the dial-up 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 dial-up 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 R2020. 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 R2020 is reset.
