Problems with pppoe...

Hello everybody. I’m a newbie of linux and opensuse and I have a problem:

Once I set up my internt connection (PPPOE), it seems to work (Kinternet syas me that it is conencted…right server, right DNS) but, even if I can ping every www, I can only surf the web on google or opensuse.org. I have also disabled the firewall to try if that was the problem but it didn’t work. I don’t know waht to do…! When I click a WWW, for example, Welcome to NVIDIA - World Leader in Visual Computing Technologies, the little icon of the internet coonection moves a while and then stops. It seems that a few data can go in/out of the network but only a few…! I think that’s the reason wht google woks and every ping works…! What can I do??

Another thing: my PPPOE conenction isn’t with a standard ethernet modem/router: Becouse I have no standard ADSL connection I have a kind of antenna that has an ethernet cable that is directly plugged in my motherboard…!

In win I have no problem to coonnect to Internet. What Can I do??
