Windows 7: bridging and pppoe

Your PC2 which is ethernet'd and has internet access can be bridged with the ad-hoc wireless connection of PC2 and PC1. The ad-hoc is basically your wireless connection using wireless adapters on both machines (hence if you have ad-hoc you can't use wifi at the same time on a single wireless adapter machine), on PC2 and the ethernet connection to the modem is the LAN.

These two can be bridged.

When you create the ad-hoc you will be asked to ICS (from memory), click yes. Make sure the ethernet connection is already internet accessed.

After you bridge the two, can you screenshot the change adapter settings, and manage wireless setting screens.

Bridged and ICS are two different things. Bridged connections are transparent. No routing. PPPoE needs routing. In order to share a PPPoE connection you have to use ICS which provides the routing needed to support your second PC. PPPoE connections only support one directly connected device, in this case it's PC2. If you want to share that connection, you need the services of a router. That's what ICS does.

thing is, the ethernet connection to the modem has no internet access on its own (you have to dial a pppoe connection first for internet access, and sharing the pppoe connection can not be done with my isp , since they block internet connection sharing!) but i am allowed to connect two pc's at the same time and i thought bridging could help (without using sharing- i thought bridging would act as a switch and not router?!)

i am able to connect my both pc's via the modem (one through ethernet and one through usb and yes both dial in at the same time through the same modem thrugh pppoe to the isp,) but my modem (a webstar 2000 series) doesnt have a windows 7 64 bit compatible driver, so im left with the ethernet interface only

Going back to the initial post, did i read right that you can't connect to the internet with PC2, with PPPoe setup on the modem ???

the modem doesnt have a pppoe connection setup (i cant connect the modem to the isp with pppoe , thats disabled, i have to use windows pppoe dialer - so in a way the modem acts as a bridge to the isp), i can connect to the internet with pc2 (the one in the middle) via pppoe on that pc, but not with pc1 which is connected to the modem via the bridged connections on pc2

This is why you can't use bridged.

im sorry, why? cus if i get a switch then this thing will work just fine (tried at a mates), the weird thing is that why doesnt the windows connection bridge act as a real bridge =/

Ok i see what you mean now. Can you screenshot your Network connections?

whats there to screenshot lol, just two bridged connections showing as a new bridge connection...
i 'solved' my problem by using proxy software and proxy cap (tunnling all traffic through proxy) but this is not the best solution as many apps dont work (because dns cant resolve hostnames)

It IS acting as a real bridge. That's why the PPPoE isn't working. Bridged mode is like a switch. No IP protocol. By enabling bridged mode you turn the ethernet port and WiFi radio in PC into a switch. If that's so, then where does the PPPoE come from? The answer is nowhere!

If you tried at your friends house, where was the switch connected?
