Connection profile
for Router B
for Router C
ISDN Router with connection profiles for Routers B and C (see the
following table).
Remote IP address
a.b.c.128
a.b.c.248
The Netopia ISDN Router's connection profiles for Routers B and C
create entries in its IP routing table. One entry points to the subnet
a.b.c.128, while a second entry points to the subnet a.b.c.248. The
IP routing table might look similar to the following:
Network Address-Subnet Mask-----via
Router------Port--Age--------Type------

0.0.0.0

127.0.0.1

UPDATE
Let's see how a packet from the Internet gets routed to the host
with IP address a.b.c.249, which is served by Router C. The packet
first arrives at Router A, which delivers it to its local network
(a.b.c.0). The packet is then received by the Netopia ISDN Router,
which examines its destination IP address.
