Re: Any luck with Netopia instalation? I have all the info, now I just have to wait for my line to get swapped.
For those wondering about your mutliple IPs - while obviously I can't speak from experience with this setup, all of the necessary bits appear to be there. I'll agree there's a rather lousy job of documentation in the package, so if you haven't been swapped yet I suggest you go check your Covad login _now_ and copy down the technical details (your PPPoE username/password, your IPs, your netmask, etc).
That said - look at the info provided on Covad's site (there's a fine example further up the thread). There are two IPs; x.y.z.17, x.y.z.16 . The lower one is your "Network Address" aka the 'all zeros address'. You probably won't have to type that number in anywhere, because it can be computed from the other information provided.
The higher of the two numbers is the IP address of the LAN side of your Netopia. When you're configuring this into the router, this will be the IP address of the router. At that time you'll also be asked for the netmask. The netmask is the key - if you do indeed have a multiple IP configuration your netmask will be 255.255.255.248 (vs. the very commonly encountered 255.255.255.0).
More technical stuff here: For people familiar with CIDR notation, using the above example, the CIDR notation of the LAN side of things would be x.y.z.16/29 (aka "a slash twenty-nine"). How can you determine how many addresses you have from this and what are they?
From the above, you know your netmask is 248. The maximum value for any of the four numbers that make up (an IPv4) address is 255. 255-248 = 7, so there are 7 'addresses' availble, however not all can be used by your equipment. IP networking requires a 'network' address (aka the "all zeros" mentioned above) and a 'broadcast address' (aka the "all ones" address). The all zeros address you know - x.y.z.16. To determine the all ones address, add 7 (the result of 255-248) to 16 (your network address) = 23. So your broadcast address is x.y.x.23.
We've accounted for two IP addresses so far - .16 and .23. Remeber that Covad gave you another IP address in the information they provided, in our example here that would be x.y.z.17 - the IP address of the LAN side of the router. What's left? Your promised 5 IPs - you can put machines on IP addresses x.y.z.18 to x.y.z.22.
Hopefully this combined with the other information in the thread above will make the transition a bit easier. All I ask is that if you found this useful, you cross your fingers and hope my cutover goes smooth :-D |

Highland Park, IL | Nice recap  My line is supposed to get switched today, but I'm guessing it won't happen now. It's ironic to wait for a line to go dark. I'm hoping to get off of interleaved since my stats are (from cisco 678)
Status:
Local SNR Margin: 38.0dB
Local Coding Gain: 6.5dB
Local Transmit Power: 12.5dB
Local Attenuation: 18.0dB
Remote Attenuation: 10.5dB
and my gaming skills are so bad that I need to recover the extra 10ms latency. |

chuckhead as an example below:
IP given to me by Covad:
66.143.64.125 =IP address of the LAN side on Netopia?
66.143.64.124 = "all zeros address"
.124 + 7 = .131 = "broadcast address?"
so 5 IPs would be from .126-.130?
so would it be correct to say:
Static IP: 66.143.64.126
Subnet Mask: 255.255.255.248
Gateway IP: 66.143.64.125 ?????
I'm confused as to what the IP to use for Gateway? Is it the 125, 124 or 131 based on the example above? |

Highland Park, IL | No, ignore the WAN side. It gets its info from PPPo*. 66.143.64.125 is the router address on the LAN side. |

| reply to crashnburn
Yep, that's correct assuming:
Static IP: 66.143.64.126
Subnet Mask: 255.255.255.248
Gateway IP: 66.143.64.125 ?????
is the information you are looking to configure into one of your client hosts (the .125 address is the address of the Netopia router and thus would become the default gateway for other client systems you connect to it) |

It's up, moderately painless. I preconfigured the Netopia last night (static info, disable DHCP on the LAN side, etc.). I think at 9am on the dot my MCI connection went dead; wandered downstairs, swapped routers, reconfigured my other firewall/bastion host with it's new IP, and once I fixed a typo in my PPPoE password (doh!) it came right up.
DNS is boned up right now for me though, but I'm pretty sure that problem is on my side, not Covad's (I probably typoed a netmask or something - never reconfigure before the first cuppa). Thumbs up for things "just working" when configured correctly, thumbs down for really lousy documentation. If I wasn't a sysad by trade I can imagine a huge amount of frustration being generated by folk trying to self-install this kit (but hey, that's one of the reasons this forum exists, right? )
For those interested in such things:
Downstream Upstream
Max Allowed Speed (kbps) 1536 768
SN Margin (dB) 26.50 5.50
Line Attenuation (dB) 38.50 23.50

On the Netopia it appears that I have to use the WAN side. Otherwise I wouldn't be able to get out. The router address on the LAN side is 192.168.1.1. |
|
| reply to chunkhead
can someone please verify if the setup above/below is correct for the Netopia router? I was just unclear as to what to put as static as shown. |
|
| I don't think that's correct. The IP-type information for the WAN interface should be 0.0.0.0 across the board; that information will be provided to the router from the other end once the PPPoE negotiation is complete. The information you have on there now should be on the LAN configuration side. |
|
| so for the picture above I should have:
static IP: 0.0.0.0
Gateway: 0.0.0.0
What about protocol? Is it correct. And bridging is disabled? |
|
| Protocol and bridge settings match what I'm using so I'd say yep, those are correct. |
|
| i havent really had any problems with setting it up.
but my line speed has really been flutuating, and i think covads dns servers are overloaded or something cause sometimes i cant dns sites. and i get a lot of time outs.
these are the settings i have,

No it's not. Before I can connect the cisco to my DLINK 624 and it worked fine. Now I call Covad and they got MORONS answering the calls and I am spending the whole day on this with no answer. I better get some answers from Digizip tommorow or I am out too. |

Your upload appears to have lots of errors. I'm assuming low SNR dB means that it's bad. |

So far, I've had no problems with the hardware and my lan setup. 11 hour uptime so far. Ping times with no traffic is better, but add any traffic, they shoot up faster than before.
The only downside of the switchover is that my upload speed has dropped 150kps. That is disappointing. I was getting at least 650kps with MCI. At least there are some Covad techs in the forums. I don't think there were any MCI techs around here. |
