Connecting a BEFW11S4 Linksys Router to Motorola Surfboard

I am trying to connect a Linksys wireless router to an existing
Motorola Surfboard SB5100 Cable modem in order to use wireless.

I have connected the Ethernet port on the Motorola to the first
Ethernet port of the "LAN" ports, like connecting two hubs. If I
connect my PC to second Ethernet port on the Linksys the internet
connection works fine - proving that the connection between the two are
fine. My PC is given my DSL IP address, 84.x.x.x

When I connect via wireless to the Linksys I cannot use the internet;
this might be due to the fact that the wireless card is provided an
internal 192.168.x.x address provided by the router, and not the public
IP address.

What do I need to do to make this work? Maybe I need to create a
static route between the 192.168.x and 84.x networks on the linksys?

Any help would be appreciated. Hutton

You should connect to the WAN port of the Linksys.

You would need a cable modem configuration that supplied more than one IP
address. If you connect to the WAN port of the router instead of the LAN
port, all of the PCs will get addresses supplied by the router, and appear
to the cable modem at a single IP address, the one you are now seeing on on
PC.

You might need to clone the MAC address of the working PC into the router.

Wrong.

Yep. Your creative wiring has effectively turned your BEFW11S4 into a
hub. Nice work.

Also due to the fact that there's nothing connected to the WAN port on
the BEFW11S4.

Start by reading the instructions. That's the little piece of paper
included with the router full of legal disclaimers and aritistic
renderings of what you have in front of you. There should be a
pictorial of where the wires and cables go.

Basically, you run a cable from the SB5100 ethernet port to the WAN or
Internet port on your BEFW11s4. You plug your computah into one of
the LAN ports. Point your web browser to:
http://192.168.1.1
and check the "Status" page. It should show your 84.xxx.xxx.xxx
routeable IP addresses from your ISP. The rest is configuration which
should be in the instructions.

The router came with a manual and you should read it.

The link shows what a NAT router does if you use it correctly.

Thanks for your help Clarence, I'll take a look. Hutton
