IPX Routing
Like IP routing, the Express 4110/4120 can connect to two different sites
and exchange IPX packets. Network routes and services are learned and
advertised using Novell’s RIP and SAP. Routes and services learned from
a separate site can be retained in the Express 4110/4120 when the connec-
tion goes idle. While retained, the Express 4110/4120 can spoof RIP/SAP
and watch-dog and filter serialization packets that would normally be
required between the Novell server and client.
Connection List - Simplifying and Enhancing the Dial Function
The Connection List, which is accessed from the Configuration menu,
provides a location to define information regarding 15 individual desti-
nations that may be dialed. A Connection List entry is required for each
destination since authentication information (method, username, pass-
word), number of B-channels, telephone numbers, Caller ID, IP, or IPX
address (for routed connections), and other information can be stored for
each destination defined. Defined destinations may be dialed by select-
ing the Dial activator in the Dial menu or by demand for the desired
Connection List profile.
Concurrent Routing and Bridging
The Express 4110/4120 can route IP and IPX as well as bridge non-IP/IPX
packets simultaneously. The Connection List profile will by default nego-
tiate PPP network protocols to support the transmission and reception of
IP, IPX, and Bridge packets. If the PPP peer does not accept a protocol, the
Express 4110/4120 will fall back to any combination of routing and bridg-
ing.
Routing over PPP Bridging
The Express 4110/4120 can support legacy equipment which does not
support PPP IP (IPCP) or IPX (IPXCP) protocols by allowing routing
packets over the WAN connection using PPP Bridging (BCP). To perform
this, the Express 4110/4120 uses a “virtual” Ethernet port. This port is set
up under the Configuration/Bridge menu.
