bridging and pppoe

[zhuki]

modem connected with ethernet to switch and pc's connected to switch , 2 pc's can dial at the same time that way (this is what isp allows, unless you have more usernames/passwords then you can connect more)
pppoe to work afaik you dont need an ip assigned in order to dial, it uses pppoe network discovery which sends a broadcast packet (layer 2 packet) to which the isp will responde and eastablish the connection, i never have an ip on my other pc configured to dial the connection and no dhcp either.

He is creating a direct dial-up connect using the "Set up a dial-up connection" option. And this has worked (PC access internet fine). He then wants to bridge this connection to a wireless ad-hoc connection create on PC2 for PC1 to connect.

Is this correct?

Also, when he says PPPoe connection, he meant the setup of the dial-up. Is this also correct?

In that configuration the ethernet ports are set up normally with PPPoE enabled. Each PC has it's own connection direct to the modem. That's why it worked.

Bridged mode however just doesn't work that way.

Try ICS on PC2. Set the ethernet port for PPPoE as you normally do when you connect to the modem. Then share it with ICS and the WiFi adapter.

Use the tutorial I referred to earlier.

Good Luck!

not the dialup connection, but the broadband connection.
and right, the pc in the middle connects fine but i dont even care if that is connected, i want the other pc (pc2) to connect to the internet through the bridged connection to the modem.
and by modem i mean , cable modem (not dialup via phone line :S)

EDIT:

Right exactly, but you mean that pppoe is disabled with windows bridging , shouldnt a bridge work the same way as a switch? (direct connection to modem?)
and unfortunately i tried internet connection sharing , but that is blocked by my isp i can only ping their server im connected to with the sharing but nothing else past that ( they blocked it with ttl - or the hop counts)
oh well i guess proxy is fine...

PC1 ->(wifi)-> [PC2 (wifi bridged with lan)]->(lan)-> ISP modem -> isp

1) PC1 ---wifi -- > PC2 (this wifi is an ad-hoc wifi, correct?)

2) PC2---LAN---> ISP modem (ethernet, using either DHCP or static, correct?)

3) ISP Modem --- > ISP (PPPoe setup, correct?)

4) Bridging connections for 1) and 2), correct?

A bridge will work like a switch but in your case you don't have it connected the same way. You're passing through PC2 to get to the modem. PC2's ethernet port can't be bridged and support PPPoE at the same time.

its ad-hoc right, and no DHCP or static (modem isnt connected to internet , i have to dial up the broadband connection from pc)

This broadband connection is off what device, USB modem, wifi??

ok i get it then, thats a shame then. This doesnt mean that windows bridging "physically" (if i may say so) bridges the two adapters, it is then filtering the data passing through it (in this case pppoe data - thats what i noticed with wireshark).
so no way around this? (except an access point of course)

well thanks for your help and time

lol you dial the broadband connection to access internet. i got a cable modem and theres no internet on the middle pc, i wanted to use that just a switch to pass the data directly to the modem from PC1 but it seems as that is not possible.

 

[aem]

You dial the broadband connection out of thin air? Do you have a build modem or some device that allows you to dial this connection?

 

[zhuki]

the middle PC (this case PC2) is connected directly to the cable modem which (the modem) is operating in bridged mode and alows the computer (PC2) to send discovery packets in the isp network. of course it doesnt dial out of 'thin air', this is how pppoe simply works. The modem or pc2 doesnt have an ip assigned to it nor is dhcp runnnig, again that doesnt matter because its just how pppoe works too. once you establish a pppoe connection you get an ip assigned and dns and all that but in the new pppoe connection (the lan connection to the modem will never have an ip assigned). The modem does have a local IP but that is just for configuration, which i cant do anything with because it is locked by the isp too. Also i found out that the modem has an isp level network adress (which is hidden from visibility on the setup pages) that is used for it to communicate with isp tftp servers to receive software updates and configuration updates , nothing else.
i Dial the connection through the pc connected directly to the modem (doesnt not matter what ip i have on that interface, itll work, as long as it is connected directly to the modem or through a switch which is directly to the modem, it just isnt working through windows briging).
I hope you understand now.
cheers

Thank you, regardless of how you dial up/connect, there is a device called a modem (can be in various form and connection type) that you go thru inorder to get to your ISP (speaking from a home environment).

This connection is good with internet doesn't matter how many devices it goes thru to get internet, it is still a connection for PC2 - a "LAN" connection?. This LAN connection on PC2 should be able to be used as one of a bridging connection if it is recognised as a LAN connection (if not, then what is it showing as in your network connection?).

A LAN connection can be bridge with a Wireless network connection, where W7 has defined your particular LAN connection as one, or something else, that remain to be seen...in Network Connections.

 

[zhuki]

its a a lan connection, and it is showing as one under network adapters. And the bridging works just fine ( i first had that message you have posted, but that was because i had internet sharing enabled -which wouldnt work, so i disabled that and the bridge between wireless and lan connection was set up successfully), the pc2 in the middle has no internet connection whatsoever but it can dial a connection through the ethernet port (lan) which is connected to the cable modem, but i dont want to dial it from that pc (the middle one in this case, pc2) but i want it to be dialed from pc1 , which is connected over wifi (ad-hoc) to pc2 , where on pc2 , the wireless adapter and ethernet adapter are bridged (thus connecting a straigh connection for pc1 to the cable modem).
idk what clearer than this to explain

 

[zhuki]

Right, heres a little graph i put together, maybe itll help you understand my problem a little more.

 

[UnTitled]

Hello...
Rofl its so funny how you try to explain how your setup works but i have the same problem with my network setup its almost the same as yours but i connect with wifi to my router and then from pc 1 to pc 2 with Ethernet as far as I know the bridge of the two connections confuses the pppoe connection or something like that .

Let me know if you got it to work.
