Or at least, I think it's weird.<br /><br /> Client has a phone tail (J11) coming into a little Netcomm NB6 ADSL2+<br /> router/modem. The Netcomm is on, and the ADSL light is lit up. The<br /> Netcomm is not attached by any means to anything else (and is not a<br /> wireless router). Specifically, there is no Ethernet connection to the<br /> Netcomm. Just power and an RJ11.<br /><br /> Client has another link to the Internet. I'm not sure what it is, but<br /> since he can definitely get to the Internet and the Netcomm is not<br /> locally networked with anything, it seems to me I can be reasonably sure<br /> it's not the Netcomm, right? Hm. Read on.<br /><br />
There's a Cisco 800 series router sitting there too; it's showing DSL<br /> "CD" on, and RX/TX is showing lots of activity. Another RJ11 tail runs<br /> into the Cisco, and this has an old piece of cardboard tied to it saying<br /> "New ADSL connection" and a phone number (yes - THAT sort of client).<br /> I'm guessing that's the Internet connection, but it's only a guess. It<br /> can't be the Netcomm, so it must be the Cisco, right?<br /><br /> Well, maybe not. The client has a symmetrical DSL link from Telstra to<br /> an office in another town. Maybe the Cisco is handling that? In which<br /> case what's handling the Internet connection?<br /><br /> Anyway, none of that is weird, that's just general ignorance. No; what's<br /> weird is that if I turn off the Netcomm, the client loses Internet<br /> connectivity. The Cisco's CD light stays on.<br /><br /> About the only explanation I can think of is that somehow the external<br /> IP address of the Netcomm is involved in routing
traffic to the client.<br /> I can't imagine how, though. I just can't believe that the Netcomm IS<br /> the Internet connection - with no Ethernet connected, no PPP light<br /> showing and (obviously) no Ethernet activity.<br /><br /> I'm not seeking help here, I'm just fascinated by the fact that this<br /> Netcomm, not networked locally at all, can somehow affect the local<br /> network's Internet connectivity on (presumably) a completely other ADSL<br /> link. I didn't think that was possible, but clearly it is.<br /><br /> Obviously I'm about to learn something :-)<br /><br /> Regards, K.</blockquote><br /><br /><hr /><br />AusNOG mailing list<br />AusNOG@lists.ausnog.net<br /><a href="http://lists.ausnog.net/mailman/listinfo/ausnog">http://lists.ausnog.net/mailman/listinfo/ausnog</a><br /></pre></blockquote></div>
