IPX/Type 20 Packets
Write security: 3; Read security: 5
In order for certain protocol implementations, like NetBIOS, to function
in the NetWare environment, routes must allow a broadcast packet to be
propagated throughout the IPX networks. The Type 20 IPX packet is
used specifically for this purpose. This causes special handling of this
packet by the Express 4110/4120. When a router receives this type of
packet, it rebroadcasts it across all interfaces except the one it is received
on and includes the network number of that interface in the data portion
of the packet. The IPX Router Specification from Novell notes that Type
20 packets should not be propagated across slower links with band-
widths of less than 1Mbps (like ISDN). However, when set to Pass (def),
the Express 4110/4120 will allow these packets to propagate over the
WAN connection. This facilitates dial-on-demand applications. When
set to Block, all Type 20 packets are not propagated across the WAN con-
nection.

Bridge/Mode
Write security: 3; Read security: 5
When set to On, the Express 4110/4120 will attempt to negotiate PPP
BCP with the PPP peer. Bridging can be used even in route mode only if
the PPP peer cannot support certain PPP protocols for that particular
routing protocol. See “Bridge/WAN IP Bridge” on page 3-26 and
“Bridge/WAN IPX Bridge” on page 3-26 for further details. Default is
