Yahoo DSL and PPPoE

[Kadarin]

Anyone have their DSL configured this way? My modem is handling the PPPoE connection, i.e. my internal network is on the 192.168.2.0/24 network with an SMC router as gateway, and the modem itself has an ip of 192.168.0.1, on a separate network, and the modem itself stores the username/password combo. But it bridges the public ip it is assigned to the computer on the inside.

The weirdness comes in that my router does not think it's connected. My computer in the internal network has a static ip of 192.168.2.10 and is pointed at 192.168.2.1 as the gw, but the router itself doesn't think it has a public ip.

I can change the modem setting such that the router itself will handle the PPPoE connection, but it seems to be stable now, so...

I have my Grandma set up with SBC Yahoo DSL. She has a Speedstream modem that is making (and keeping) the PPPoE connection and a netgear router behind it. The router is set to obtain an IP automatically and to distribute IP addresses to the LAN. Her modem has a non-routable IP as well as the public IP. The router does recognize that it has a public IP though. I'm not sure if this is what you're dealing with also or not.

It is. Oddly, the router now shows that it's got a public ip. If I release/renew dhcp, however, it'll show disconnected. Nothing's wrong, it's just that I've never seen pppoe handled this way before. 🙂

I wonder what you mean by

[/quote]...but the router itself doesn't think it has a public ip.

Are you saying that when you look at the router configuration and what is shows for WAN Ip is not a public IP address?


This is very common for PPPOE connections. You will especially notice it on computers connected directly to modem.
When doing ipconfig you will see the public ip is actually on the pppoe adapter and not the physical ethernet adapter.
