Netbios; Ipx Spoofing; Ipx Setup - Netopia R2121 User Reference Manual

The following is a list of common SAP server types:

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 R2121 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 R2121 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

Main
Menu
The IPX Setup screen is where you configure the Ethernet side of the Netopia R2121. 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 R2121 is reset.
