Chapter 3 - IPX Routing & Bridging 63
Use Ethernet Port as End-Node Proxy
The router can be set to dynamically reserve an IPX address for this WAN
interface on an Ethernet segment. This proxy address will then be used if the
remote PPP IPX implementation requests address negotiation (generally used
by end-node clients).
Since the reserved address will be assigned to this interface, this checkbox
can only be checked on an interface set to be unnumbered.
• If checked, then an IPX address will be reserved for this WAN interface
on an Ethernet segment. The default is unchecked.
Block IPX Type 20 Output Packets
In order for some protocols, notably NetBIOS, to function in the NetWare
environment, routers must propagate a certain type of broadcast packet
throughout an IPX internetwork. IPX packet type 20 is designated to perform
broadcast propagation for these protocols.
When an IPX router receives a type 20 packet, it rebroadcasts it out all inter-
faces, except the one on which it was received. The IPX network number of
the originating interface is included in the rebroadcast packets.
This checkbox allows you to control the rebroadcasting of IPX type 20
packets on this interface. This is useful for on-demand WAN links where the
link may be brought up as a result of propagating this type of packet.
• If checked, then type 20 packets will not be propagated on this interface.
The default is unchecked.
v Note: Novell’s router specification recommends that type 20 packets not
be propagated across links with bandwidths of less than 1 megabit per second
(such as asynchronous dial-up links and 56K leased lines).
