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><a href="mailto:AusNOG@lists.ausnog.net">AusNOG@lists.ausnog.net</a><br><a href="http://lists.ausnog.net/mailman/listinfo/ausnog">http://lists.ausnog.net/mailman/listinfo/ausnog</a><br></pre></blockquote></div>
