To the server, a spoofed connection looks like a normal, active client login session, so it does
not log the client out. The timer begins counting down as soon as the link goes down. At the
end of the selected time, the MAX stops responding to watchdog packets and the server can
release the client-server connections. If the WAN session reconnects before the end of the
selected time, the MAX resets the timer.
Note: The MAX filters watchdog packets automatically on all IPX routing connections and
all IPX bridging connections that have watchdog spoofing enabled. The MAX applies a call
filter implicitly, which prevents the idle timer from resetting when the MAX sends or receives
IPX watchdog packets. You apply this filter after the standard data and call filters.
SAP HS Proxy (NetWare SAP Home Server Proxy)
By setting SAP HS Proxy parameters, you can configure the MAX to forward SAP broadcasts
to specified IPX networks, thus ensuring that remote users access the same resources as local
users.
When a NetWare client starts up, it broadcasts a SAP request for the nearest server if it is not
configured for a preferred server or if it does not get a response from the configured, preferred
server. By default, the MAX consults its own internal SAP table and responds to this request
with the SAP server entry with the lowest hop count. SAP HS proxy keeps the MAX from
making this response; instead the MAX forwards the response to the specified IPX network,
and relies on a response from a router on that network.The MAX takes the first SAP reply
received to be the nearest server, and attaches your PC to that server.
If you load your client software from another PC, or use the same PC when traveling, the
response to the initial SAP Request could attach you to a different server. With SAP HS Proxy,
you can direct SAP Requests to specific networks. The SAP Responses come from servers on
these specified networks rather than the server nearest the MAX. To configure the parameters,
proceed as follows:

Examples of IPX routing connections
This section shows sample WAN connections using IPX routing. If the MAX has not yet been
configured for IPX routing, see "Enabling IPX routing in the MAX" on page 11-5.
Configuring a dial-in client connection
In this example, a NetWare client dials into a corporate IPX network by using PPP dial-in
software. Figure 11-1 shows a corporate network supporting both NetWare servers and clients.
MAX 6000/3000 Network Configuration Guide
Open the Ethernet > Connections > any Connection profile > IPX Options profile.
Set the SAP HS Proxy parameter to Yes.
Specify the IPX network address to which SAP broadcasts will be directed. For example:
SAP HS Proxy Net#1=CB1123BC
This setting specifies that any SAP Broadcast Requests received from this user will be
directed to IPX network CB1123BC.
If you want to define other networks, repeat step 3 for
Exit the profile and, at the exit prompt, select the exit and accept option.
