PLEASE NOTE:Any gateway/router which will do PPPoE will work just fine with SBC's "sticky" PPPoE. What they won't all do is route the entire /29 (and 5 usable IP addresses) across the WAN-LAN boundary. You will get ONE, used by the LAN via the router's NAT functionality. If you want to assign public addresses to your servers on the LAN, you need a unit which has that capability along with PPPoE. This is not very hard to do with easily obtained equipment. See below.



The following routers are known to work with the SBC/Ameritech 5 Static IP PPPoE-delivered package, allowing use of all 5 IPs on your LAN. Any router that supports PPPoE and mapping addresses across to the LAN works. There are several ways to do this.

(Note: The stock Linksys, DLink, SMC and stock Netgear products will not work. Some older Netgear units can run ZyXel firmware, and they will work once the firmware is changed. See this forum post.) Some Linksys units running third party firmware work as well. See below.

Netopia/Cayman 3546 (Previously provided equipment, router & modem in one)
Efficient 5861 (Previously provided equipment, router & modem in one. Please note that this needs firmware at the .140 or later level to operate at full speed on a 6 megabit line.)
Cabletron Systems 255, which predated the 5861. This one needs upgrading to PPPoE to work and is no longer in production. Most can run 5861 code.
ZyXEL P310 (router only-you need an Ethernet modem too)
ZyXEL P314 (router only-you need an Ethernet modem too)
ZyXEL P316 Wireless Router (router only-you need an Ethernet modem too)
ZyXEL ZyWALL 10 (router only-you need an Ethernet modem too)
Note: Zyxel routers require firmware version 3.25.

SonicWall SOHO (router only-you need an Ethernet modem too)
Netopia R-6100 See this FAQ entry.
Netopia R910 See this FAQ entry.
Netopia 4541
Cisco 1700 series and maybe others (see this FAQ entry for instructions) You need a modem too.

Cayman 3220H This router & modem combo will bridge LAN devices with the public addresses while supporting NAPT. Cayman 3220H OS 6.2 or later supports mapping the public WAN addresses 1:1 to private LAN addresses.
3Com Officeconnect Remote 812 ADSL router See details in this FAQ entry.

2-wire HomePortal/OfficePortal A modem/router combo which as of the date of this revision (02/03/2005) is current equipment for many accounts. See /faq/11776 for details on how to set it up.

Netopia 3346n This is the current modem/router combo provided to static IP customers who do not want the 2-wire, preferring a more business-class product.

Linksys WRT54G running OpenWRT See »Ameritech - SBC FAQ »OpenWRT Linksys WRT54G for 5 static IP Service .

DIY If you are so inclined you can roll your own with *nix and some tools. See /faq/3028 and /faq/11695 for ideas.

If you are configuring your router, you want to set the VPI/VCI setting for 0/35 for PPPoE. This is the most common now.

If you are on an old PPPoA setup with an Efficient 3060 PCI modem, you're probably on 0/105. And if you have an ancient straight (bridged) ATM setup with no PPPoAnything, or are using an Alcatel 1000/Efficient 3010 ATM25 NIC, you could be 0/105 or 0/100. Note that the SOHO "routers" like the Linksys, Netgear, etc., will no work on anything but PPPoE or straight Ethernet (cable modem-style).

This topic in the Efficient forum covers the ports you need to forward with NAT routers, in particular the Efficient Networks units, for popular programs.

First, you need to make sure that your modem is "DMT" (discreet multi-tone) and not "CAP" (carrierless amplitude and phase) modulated. They are not interchangeable.

Second, you need to make sure that it complies with the G.DMT standards. That should be in the documentation.

Third, you'll need to make sure that it's VCI/VPI numbers are right (for Ameritech that's 0/35 for PPPoE, 0/105 for PPPoA) or can be changed to those numbers.

If it meets these conditions, it should work fine even on a linshared installation.

As long as DHCP is enabled and the computer is obtaining an IP address automatically, the routers IP address will be the default gateway displayed by a winipcfg or ipconfig command.

SBC has a web page that tracks modem compatibility with Windows XP and provides some setup information here. This only covers the modems that SBC has provided over the years.

Absolutely! It is not difficult, and it should affect your DSL connection positively!
(Also see this FAQ for other options and configurations: /faq/10443)

Obtain a splitter - You can purchase a splitter from Wilcom (1-800-222-1898) for about $35. An information sheet can be found here. Any splitter must have a 4000hz cutoff to be compatible with Ameritech's (ASI) network.
Run a wire from the Network Interface Device (NID) to the splitter - Use the best grade of cable you can obtain -- best if it is Category 5 or better. Also, keep this run as short as possible, for this is the one that carries both the DSL signal and the POTS signal.
Plug the DSL Modem into the splitter - Plug the DSL modem directly into the splitter, or run additional wire close to the DSL modem. Again, this wire should be of the highest quality (Category 5 or better), since any interference here directly affects your DSL quality.
Wire from the splitter to the phones - Plug the phones directly into the splitter, or run a cable from the splitter to the phones.
Remove any installed microfilters - If you have installed any microfilters to support your previous installation, remove them -- they are no longer necessary.

Below is my current installation, for a visual reference:

A "home run" is nothing more than a length of suitable telephone cable connected to a test jack inside a NID that has the DSL signal, that cable is routed directly to the modems location.

This Keptel pots splitter was very easy to install. It is a low pass filter and it snaps into place in a Keptel NID. Included with the splitter is a bracket which is for mounting in a Siecor NID.


As noted in the photo at one time there was a second voice line used for dial up. It had its own separate 4 wire cable (red,green,black,yellow) run to computer location. The cable has untwisted wire and the crosstalk made it unusable for more than one voice line but ok for DSL

Below is a image of the 4 wire cable
