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.

ϖNote: 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).
