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 R5000 Series Router 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 that 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 R5000 Series Router as though they came back from the user without bringing up the dial-up link.

SPX keep-alive packets are also 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.
