1) Install an Ethernet card in each computer and a second one in the server to connect to your DSLmodem2) If using Win 95 98 or ME as the server assign an internal IP to each each Ethernet card (For the cardconnecting to the modem use an address of 1000xxx and for the card in each PC use 192168xxxxxx)use these instructions
3) Make sure you use a cross over Ethernet cable between the two PCs and a straight through Ethernetcable to the modem4) If you are using XP or Windows 2000 as the server do not set an internal IP address on the twoEthernet card that connect each computer make sure they are assigned to use DHCP
1) Install an Ethernet card in each computer2) If using Win 95 98 or ME as the server assign an internal IP to each each Ethernet card use theseinstructions3) Use straight through Ethernet cables for all connections if plugging your modem in to the uplink port on
your hub If you do not have an uplink port please use a cross over Ethernet cable

bull Options menu MTU adjustment Why would one need to adjust the MTU Well if the ISP is using
Cisco LNS for example and not Multilink PPPoE the MTU is set on the Cisco at 1452 but not autonegotiated properly with the client side (fault in Cisco) The causes some web sites to not load and
most emails over 1 KB to not get sent out from the client side PC Also some ISPs who resell awholesale service may have their connections between the wholesale provider and their networkvia L2TP which add overhead causing an MTU issue also Set the MTU to 1452 on the client sideand this problem is resolved XP PPPoE needs a registry patch to adjust the MTU and must bedone in the registry file and can not be done in an options menu Not being able to adjust the MTUhas been the cause for many end users not being able to get to various web sites or send outemails over 1 KB

What is PPPoEPoint to Point Protocol over Ethernet is a proposal specifying how a host personal computer (PC) interactswith a broadband modem (ie xDSL cable wireless etc) to achieve access to the growing number of Highspeed data networks Relying on two widely accepted standards Ethernet and the point-to-point protocol(PPP) the PPPoE implementation requires virtually no more knowledge on the part of the end user other than that required for standard Dial up Internet access In addition PPPoE requires no major changes in theoperational model for Internet Service Providers (ISPs) and carriers The significance of PPP over Ethernethas to do with its far greater ease of use versus competing approaches By making high speed accesseasier to use for end consumers and more seamless to integrate into the existing infrastructure for carriers
and ISPs PPPoE could speed the widespread adoption of High speed access services
Also PPP over Ethernet provides a major advantage for service providers by maximizing integration with -and minimizing disruption of - service providers existing dial network infrastructures Through tightintegration with existing back office automation tools that ISPs have developed for dial customers PPPoEenables rapid service deployment and cost savings From authentication accounting and secure access toconfiguration management PPPoE supports a broad range of existing applications and services
The base protocol is defined in RFC 2516
Why would PPPoE be usedPPPoE is used to allow Internet Service Providers (ISPs) the use of their existing Radius authenticationsystems from their Dial-Up service on a Broadband Ethernet based service Dial-Up is PPP most
broadband connections are Ethernet hence Point to Point Protocol over Ethernet It also allows for ISPs toresell the same line multiple times IE Rated services Broadband specific content (movies etc) meteredservices etc
Will there be any changes to how I use my High Speed ServiceInstead of having the connection automatically occur when your computer boots (using DHCP for exampleto obtain an IP address) you would have to connect using PPPoE software like WinPoET or maybe a router that will handle it for you Once you are connected using the client your connection will look feel thesame as your current connection When you are finished or when youve been idle for an undisclosedperiod of time the client software may disconnect you and you will need to reconnect to gain access to theInternet again
Will there be a speed difference if my ISP switches to PPPoEThis is a difficult question to answer The definition of the protocol points to a 5-10 decrease in bandwidth
as extra data will need to be sent down the line to handle the PPPoE signaling There may be other penalties as well derived from the server-side implementationIf you look at this from a mathematical stand point PPPoE adds 8 bytes of header to the standard 1500 byteMTU packet With this in mind you are only reducing speed by 3 (Yes 3 of one percent) So will you see aspeed decrease no you probably wont

No in fact it will lower them You can have your PC up and running but not connected to your ISP if youchoose to disconnect with your PPPoE Software leaving you no longer vulnerable to and Internet Attacks
What is PPPoE3Com (Or what has 3Com done to the PPPoE protocol)Simply put 3Com has created a proprietary version of the PPPoE protocol It is only used when your 3ComDSL modem is set to PPPoA mode When this happens it speaks PPPoA to your ISP but then speaksPPPoE to your computer (That is why they bundle a PPPoE client with their DSL modems)
3Com has changed these two valuesETHER_TYPE value for PPPoE Discovery phase Changed from 0x8863 to 0x3c12ETHER_TYPE value for PPPoE Session phase Changed from 0x8864 to 0x3c13Will this effect the use of a router Yes A few routers now support this new version only used with 3ComDSL modems in PPPoA mode
Is AOL PPPoE differentOriginally AOL was using a proprietary version of a PPPoE application called WinPoET This is no longer thecase they are using their on PPPoE application but it is ldquostandardsrdquo compliant
What network interface does PPPoE requirePPPoE applications require an Ethernet adapter with TCPIP bound to it This could be an Ethernet card aUSB to Ethernet adapter or simple a USB DSL modem
Can PPPoE be made to connect on boot for my PCMost PPPoE applications such as WinPoET do have the feature to connect on Windows Startup
How does PPPoE give me an IP addressBasically when you click connect on your PPPoE application or when your router begins to connect to your ISP a discovery process occurs to ask for a connection A session is then created Your userid and passwordis then authenticated via Radius Your IP DNS etc is the assigned via a process similar to DHCP (IPCP)
Can you explain the PPPoE discovery stageThe PPPoE Discovery Stage is made up of four steps initiation offer request and session confirmation
1)The PPPoE Active Discovery Initiation (PADI) packetThe PPPoE client sends out a PADI packet to the broadcast address This packet can also populate the
service-name field if a service name has been entered on the dial-up networking properties of the PPPoEbroadband connectoid If a service name has not been entered this field cannot be populated
2) The PPPoE Active Discovery Offer (PADO) packetThe PPPoE server or Access Concentrator should respond to the PADI with a PADO if the AccessConcentrator is able to service the service-name field that had been listed in the PADI packet If noservice-name field had been listed the Access Concentrator should respond with a PADO packet that hasthe service-name field populated with the service names that the Access Concentrator can service ThePADO packet is sent to the unicast address of the PPPoE client
3) The PPPoE Active Discovery Request (PADR) packetWhen a PADO packet is received the PPPoE client responds with a PADR packet This packet is sent to theunicast address of the Access Concentrator The client may receive multiple PADO packets but the clientresponds to the first valid PADO that the client received If the initial PADI packet had a blank service-name
field filed the client populates the service-name field of the PADR packet with the first service name thathad been returned in the PADO packet
4) The PPPoE Active Discovery Session-confirmation (PADS) packetWhen the PADR is received the Access Concentrator generates a unique session identification (ID) for thePoint-to-Point Protocol (PPP) session and returns this ID to the PPPoE client in the PADS packet Thispacket is sent to the unicast address of the client

How does PPPoE give me an IP addressBasically when you click connect on your PPPoE application or when your router begins to connect to your ISP a discovery process occurs to ask for a connection A session is then created Your userid and passwordis then authenticated via Radius Your IP DNS etc is the assigned via a process similar to DHCP (IPCP)
Can you explain the PPPoE discovery stageThe PPPoE Discovery Stage is made up of four steps initiation offer request and session confirmation
1)The PPPoE Active Discovery Initiation (PADI) packetThe PPPoE client sends out a PADI packet to the broadcast address This packet can also populate the
service-name field if a service name has been entered on the dial-up networking properties of the PPPoEbroadband connectoid If a service name has not been entered this field cannot be populated
2) The PPPoE Active Discovery Offer (PADO) packetThe PPPoE server or Access Concentrator should respond to the PADI with a PADO if the AccessConcentrator is able to service the service-name field that had been listed in the PADI packet If noservice-name field had been listed the Access Concentrator should respond with a PADO packet that hasthe service-name field populated with the service names that the Access Concentrator can service ThePADO packet is sent to the unicast address of the PPPoE client
3) The PPPoE Active Discovery Request (PADR) packetWhen a PADO packet is received the PPPoE client responds with a PADR packet This packet is sent to theunicast address of the Access Concentrator The client may receive multiple PADO packets but the clientresponds to the first valid PADO that the client received If the initial PADI packet had a blank service-name
field filed the client populates the service-name field of the PADR packet with the first service name thathad been returned in the PADO packet
4) The PPPoE Active Discovery Session-confirmation (PADS) packetWhen the PADR is received the Access Concentrator generates a unique session identification (ID) for thePoint-to-Point Protocol (PPP) session and returns this ID to the PPPoE client in the PADS packet Thispacket is sent to the unicast address of the client

You can also just disable DHCP on NT and 2000On NT Go to Control Panel-gtServices -gt Find the DHCP Client and Disable itIn Windows 2000 go to Administrative tools -gt Services there you will find an option to disable it Note InWindows 2000 I am finding out that with an internal DSL modem you can not change from DHCP or even
disable it You have to leave DHCP as is
I can not get to all web sites or send emails with attachmentsYou probably need to change the value for your MTU on the PC this can be done usually directly in thePPPoE client like WinPoET or you may have to do it in the router or modem that is doing your PPPoE for you I recommend 1452 if you are having this problem
I just got a new Bell Atlantic line and get Error 629This is because your profile has not been built yet by the ISP contact them for further help
I use Internet Explorer and get a No Connection Try Again error With Win 98 Go to addremove programs Select IEx and then remove Select Repair or you can update to anewer version of IE
You can also try downloading the Off-line Browsing package available from the Windows update site
Or you can tryDownload this Registry file to your desktop2) Right click on it and choose Install or MergeOr you can try thisIf you have installed MSN uninstall it and then try out the following1) Close all Screens and disconnect from the internet2) Click on Start -gt Settings -gt Control Panel -gt Internet Options -gt Connections Tab -gt Setup Button3) Select I want to connecting manually -gt Click Next4) Select I want to connecting by a LAN -gt Click Next5) Make sure there is nothing selected in the Automatic Proxy Configuration window -gt Click Next6) Select No for the Do you want to setup a mail account now window -gt Click Next7) Uncheck To connect to the internet immediately select this box and -gt click Finish
8) You should be back to the Control Panel -gt Double Click on AddRemove Programs9) Find Microsoft Internet Explorer -gt Double click on it _gt Then Choose Repair
I get an error every time I try to add a new instance of TCPIP Your system allows only X instancesof X1) Use any text editor (such as Notepad) to view the Nettransinf file in the WindowsInf folder2) Increase the MaxInstance entry for the appropriate protocolNote that the maximum number for this entry is 83) Save the changes to the Nettransinf file and then quit Notepad
Im using Windows Media Player 7 and it wont connect to anything This registry file forces WMP to be online and should fix the problem always back up your registry beforemaking changes

What is PPPoEPoint to Point Protocol over Ethernet is a proposal specifying how a host personal computer (PC) interactswith a broadband modem (ie xDSL cable wireless etc) to achieve access to the growing number of Highspeed data networks Relying on two widely accepted standards Ethernet and the point-to-point protocol(PPP) the PPPoE implementation requires virtually no more knowledge on the part of the end user other than that required for standard Dial up Internet access In addition PPPoE requires no major changes in theoperational model for Internet Service Providers (ISPs) and carriers The significance of PPP over Ethernethas to do with its far greater ease of use versus competing approaches By making high speed accesseasier to use for end consumers and more seamless to integrate into the existing infrastructure for carriers
and ISPs PPPoE could speed the widespread adoption of High speed access services
Also PPP over Ethernet provides a major advantage for service providers by maximizing integration with -and minimizing disruption of - service providers existing dial network infrastructures Through tightintegration with existing back office automation tools that ISPs have developed for dial customers PPPoEenables rapid service deployment and cost savings From authentication accounting and secure access toconfiguration management PPPoE supports a broad range of existing applications and services
The base protocol is defined in RFC 2516
Why would PPPoE be usedPPPoE is used to allow Internet Service Providers (ISPs) the use of their existing Radius authenticationsystems from their Dial-Up service on a Broadband Ethernet based service Dial-Up is PPP most
broadband connections are Ethernet hence Point to Point Protocol over Ethernet It also allows for ISPs toresell the same line multiple times IE Rated services Broadband specific content (movies etc) meteredservices etc
Will there be any changes to how I use my High Speed ServiceInstead of having the connection automatically occur when your computer boots (using DHCP for exampleto obtain an IP address) you would have to connect using PPPoE software like WinPoET or maybe a router that will handle it for you Once you are connected using the client your connection will look feel thesame as your current connection When you are finished or when youve been idle for an undisclosedperiod of time the client software may disconnect you and you will need to reconnect to gain access to theInternet again
Will there be a speed difference if my ISP switches to PPPoEThis is a difficult question to answer The definition of the protocol points to a 5-10 decrease in bandwidth
as extra data will need to be sent down the line to handle the PPPoE signaling There may be other penalties as well derived from the server-side implementationIf you look at this from a mathematical stand point PPPoE adds 8 bytes of header to the standard 1500 byteMTU packet With this in mind you are only reducing speed by 3 (Yes 3 of one percent) So will you see aspeed decrease no you probably wont
Will PPPoE affect any Internet applications such as ICQThe protocol has been out now and in use for over 5 years All internet apps can now be made to work withPPPoE
Does PPPoE increase security risks with my broadband connection

No in fact it will lower them You can have your PC up and running but not connected to your ISP if youchoose to disconnect with your PPPoE Software leaving you no longer vulnerable to and Internet Attacks
What is PPPoE3Com (Or what has 3Com done to the PPPoE protocol)Simply put 3Com has created a proprietary version of the PPPoE protocol It is only used when your 3ComDSL modem is set to PPPoA mode When this happens it speaks PPPoA to your ISP but then speaksPPPoE to your computer (That is why they bundle a PPPoE client with their DSL modems)
3Com has changed these two valuesETHER_TYPE value for PPPoE Discovery phase Changed from 0x8863 to 0x3c12ETHER_TYPE value for PPPoE Session phase Changed from 0x8864 to 0x3c13Will this effect the use of a router Yes A few routers now support this new version only used with 3ComDSL modems in PPPoA mode
Is AOL PPPoE differentOriginally AOL was using a proprietary version of a PPPoE application called WinPoET This is no longer thecase they are using their on PPPoE application but it is ldquostandardsrdquo compliant
