1 This seems to be similar to the dlink adsl modem I am using (no routing
2 function).

4 Think of the 192.168.0.0 network as being the network between the modem
5 and the gateway machine. In my case, the 10. (equiv) networks are on
6 the internal side of the gateway. My gateway machine runs dhcp on eth0
7 (the 192.168.0.0/24 network). When the adsl modem is unlocked, I get a
8 192.168.0.2 address from the adsl modem. When locked, the 192.168.0.2
9 is replaced by the ISP allocated address. The default gateway then
10 becomes the *ISP end* (far) of the adsl connection, and is normally set
11 by dhcp on your gateway machine. The modem web server is always
12 reachable via 192.168.0.1, even after the ISP allocated
13 addresses/gateway are set.

15 In my case
16 1) ISP -> unlocked -> adsl modem -> 192.168.0.1 -> 192.168.0.2 ->gateway
17 -> 192.168.1.x
18
19 2) ISP -> x.x.x.x -> adsl modem -> x.x.x.(x-1) -> gateway -> 192.168.1.x

21 -> 192.168.0.1 ->
22 Edited route -n for my gateway:

36 the .43 is a wireless network
37 the x.x.x.x is my ISP dhcp allocated IP as set by dhcp running on my
38 gateway.

40 I would steer clear of adding anything else to the 192.168.0.0/24
41 network as (in my case) things dont always work as expected (with an
42 accidental misconfiguration, I ended up with "wild" packets present on
43 my internal network).
