SBC Speedstream 5100b Router Network Question

[Doug]

I just got the Speedstream 5100b router/dsl modem which uses
192.168.0.1. I have a pre-existing internal network which uses
192.168.0 so won't there be a conflict? What is the best way to
resolve this? Thanks, Doug

If you plug this DSL/Router combo into the WAN side of your
existing router you will be double NAT'd which will be unreliable
or may not work at all if they are both set to use 192.168.0.*
numbers. You can either;

a) Turn off the Router/PPPoE function (using DSL bridge-only mode)
of the Speedstream and connect it to the WAN port of your current
router and use that for DHCP (and PPPoE, if you have dynamic DSL).

b) Turn off DHCP/PPPoE of your current router and connect
the Speedstream to a LAN port (this may require a cross cable,
but I am not sure). In this configuration your current router will
be functioning as a switch only and your PCs will be getting DHCP
info from the Speedstream.

I've done it both ways but I prefer choice a). I had to use choice
b) a few times, for example, if the DSL router does not allow
operation in bridge-only mode. More details on what you have on
your network side would help.

What is the pre-existing network? Are you using a NAT router?
Can you change the existing network address range?
You might be able to configure your existing NAT router as a normal router.
The newer Linksys routers offer this option. Then you would use NAT from
the DSL modem.

Another possibility is to turn off the 5100b router and make it the bridge
that it was before they added that fifth LED on the front.

Now I have changed my internal network to use 192.168.3. instead. And
I have removed my linksys router from the network, and instead
connected the Speedstream 5100b router/dsl modem directly to my linux
machine.

And I am able to browse the web from the linux machine. However I am
unable to browse the web, or ping any external ip from a windows XP
client.

What do I need to do to be able to browse the web from the windows
client? Did my linksys router do something to allow this that the
Speedstream does not do? Or do I need to configure the Speedtream
differently? Thanks, Doug
