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 R7200 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 R7200 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.
IPX setup screen
Main
Menu
You will use the IPX Setup screen to configure the Ethernet side of the Netopia R7200. The information you
enter controls how the router routes IPX traffic.
Before changing any of the settings in this screen, consult your network administrator for the IPX setup
information you will need. Changes made in this screen will take effect only after the Netopia R7200 is reset.
