Multiple Connections from a Single Site
In some instances it is likely that you will need to connect to Novell servers
on one site, IP hosts on the same remote site or possibly a different
remote site and a connection into the Internet. This can all be achieved by
running the simple configuration several times until all the desired types
of connection have been configured. The only thing you need to be aware
of is that you cannot bridge and route the same protocol.
The local site shown in Figure 1-25 is a small business that needs data
links to several of its clients and a connection to the Internet. It has an IPX
connection to access information on one client’s NetWare server and IP
routed connections to several IP hosts at different clients’ sites. Finally,
there is a connection to the local Internet service provider’s PPP router
giving fast access to the Internet. All connections can be set up with an
autocall so that connections to the remote sites are made as soon as the
AccessBuilder 500 identifies data not destined for the local network.
