Netopia R2121 - Manual (Page 129)

IPX Setup 11-3
The following is a list of common SAP ser ver types:
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 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 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 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 ser ver 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 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.
