To go to the IPX Setup screen, from the Main Menu select System Configuration and then select Network
Protocols Setup and then select IPX Setup.
1. To enable IPX routing, select IPX Routing, toggle it to On, and press Return.
2. To change Ethernet encapsulation from the commonly used 802.3 standard, select Ethernet
Encapsulation and choose a different encapsulation method.
3. Select Ethernet Network Address and enter the network address of the IPX network connected to the
Netopia R3100’s Ethernet port.
Note: If the Ethernet network address is set to zero, the Router will attempt to learn the address from any
configured IPX device on the Ethernet network or from the remote IPX network when a call is established.
4. To change the default path delay, select Ethernet Path Delay and enter a value (in ticks). This value is used
to determine the port cost of using the Ethernet port in IPX RIP calculations.
5. To enable NetBIOS packet forwarding, select Ethernet NetBIOS Forwarding and toggle it to Yes. This
parameter will determine whether “IPX Packet type 20” packets are forwarded on the Ethernet interface.
These packets are used by NetBIOS and some other applications.
6. Select Ethernet Inbound SAP Filter Set to filter incoming IPX SAP advertisements on the Ethernet. By
attaching an incoming SAP filter on the Ethernet, you can restrict the number of SAP entries learned on a
large IPX network to only those required by remote users connecting to the Netopia R3100. An Ethernet
SAP filter must be used with networks that have so many servers advertised that the Netopia R3100 would
otherwise exhaust its internal memory storing server entries.
To attach a SAP filter set, first define the filter set using the Filters and Filter Sets option (see step 8
below). Then select the filter set from the Ethernet Incoming SAP Filter Set pop-up menu. To detach the
filter set, select Detach Filter Set.
7. Select Default Gateway Address, and enter the network address of the IPX network to which all packets of
unknown destination address should be routed.
