30 X4 ADSL Modem User’s Manual
2.9 Route Table
The X4 includes a routing table function for users who want to set
up an additional network (or networks) residing on a different
subnet than the X4. Without a route table, any computer residing
on an additional subnet would be invisible to the modem. The
route table acts as a map for the modem, so that it directs traffic to
the correct subnet location.
To access the route table function, click the
Route Table
button at
the top of the
Advanced Setup
page. You will see at least three
route table entries. (These entries are automatically displayed once
you connect the X4.) Under
Destination
, you will see the IP
address of the X4’s LAN interface (for example, 10.0.0.0), the IP
address of the local loopback test (127.0.0.1), and the IP address of
the WAN interface (for example, 192.168.1.1). Under
Netmask
,
you will see the corresponding subnet masks for these three
Destinations. Under
Gateway
, you will see the corresponding
Gateway IP addresses. The
Interface
field denotes the type of
interface; for example, br0 denotes Ethernet, lo0 denotes loopback,
and ppp1 denotes PPP (WAN).
