2x Routers to Openreach Modem??


[link to this post]
 
Hi,

From the pictures i've seen of the Openreach VSDL modem, there are 2x LAN sockets on it.

Has anyone tried connecting a 2nd router to that socket?

With my O2 Broadband connection, i'm using a Netgear router toggled into 'Modem Only' mode, connected to a Linksys WRT54GS cable router so I could keep my router and setup when I moved house from one with cable.

A while later I found that if I connected a 2nd router to one of the other lan ports on the Netgear, that router connected and got it's own external IP. Obviously both routers are sharing the same physical line so you don't get twice the speed or anything but I find this useful for having a wireless connection available with a simple WPA key for friends/family coming round, without them having access to my (completely separate) LAN with my NAS etc on and a more complicated WPA key.

Obviously this is unsupported/undocumented behaviour, but I was wondering if this would be possible on Infinity using that 2nd LAN connection on the modem.

Is anyone able to try it? - if you are using your own router, are you able to connect the BT HomeHub to the 2nd port?

Thanks,

Ian

I dont think the 2nd port on the Openreach modem is active, probably reserved for the future NGA voice service.

No can do, LAN port 2 is disabled on the Openreach FTTC modem.

On my modem, the port is covered over by a label. But that doesn't stop you putting a switch or hub between the router and modem - though other discussions reached the conclusion that this shouldn't be your LAN's switch; it needs to be a separate one.

The router I was sent by Plusnet - a netgear WNR1000 - seems to have 2 wirelass LAN configurations; one main one, and one guest one, the guest one has separate authentication, and can be denied access to your LAN. It seems the right choice of router might be enough for you...

Has anyone tried peeling away the label and connecting a router to it anyway to confirm it's actually disabled?

Interesting! - i'd not thought of that.

Do you recall where these discussions were?

If you connect a switch to the modem, then 2x routers to the switch, are both routers able to make successful PPPoE connections and get their own IP address?

Is anyone actually running this setup?

Thanks,

Ian

That wouldn't be possible unless the ISP has specifically set up the subscriber with multiple static IP addresses.

How many WAN ethernet ports are available doesn't affect the number of WAN IP addresses available on the connection I'm afraid. Also, you can't tunnel two simultaneous PPPoE connections over a single WBC ATM connection.

And Ports 3 and 4 have the connectors missing! - the board is designed with four ports.

I think what you'll find is that Huawei designed the hardware similiarly to most wired ADSL routers in that they can be configured as a transaparent bridge, PPPoE Modem, or fully functioning router.

The Openreach firmware simply locks down the "router" in PPPoE Bridge mode.
