    Hi
    I have a VPN service that I can connect to with other computers in my home network with no problem, But my leopard MBP, After connection to VPN server (pptp), the connection to internet dies. I still can ping by IP but cannot with domain names. I tried changing the DNS server of my connection but no luck.
    I have to say that this happens after I select the "Send All traffic over VPN connection" option in advanced menu.

    So to be clear, your connection to the internet did not die, you ability to resolve hostnames does.

    You said you tried changing the DNS server on your "connection," but which connection? The physical or the virtual?

    Anyhow, my guess is that this is a service order issue. If you are telling the machine to send all traffic to through VPN and VPN is at the top of the service order, the behavior will be as you are experiencing.

    To change the service order:
    1. Open Network Preferences
    2. Click the gear popupmenu on the bottom of the left pane (to the right of the + and - signs)
    3. Click "Set Service Order"
    4. Arrange the services in a way that the service providing your connection to the internet is at the top, and your VPN below it somewhere (probably as a second choice.)
    5. Click Ok, Click Apply


    After this you should be able to resolve names.

    Sorry If i wasn't more clear. Yes I have problem regarding resolving hostnames.
    I have changed the order of my connections but I still have the problem.
    I think the problem is with my routing.
    I think I should change my dns and search domain, but I don't know change it to what?

    Your VPN is the issue because you are doing full tunneling. You need to configure the server side of the tunnel to allow VPN hosts to point to the internal DNS servers, and allow those system to access the Internet.

    I don't think server is the problem because I was using it on my linux box with no problem also in windows.
    I think its something regarding changing DNS because I can ping IP addresses but not domain names.

    Then what DNS server is your Mac pointing to? It will need to point to the DNS servers across the tunnel.

    Sorry for my last post. I checked other computers on network and it seems they are having the same problem. There were no problems this morning. So I think its server problem I guess. I use poptop on my server side. What could be the problem? Is it irrelevant for this forum?

    I checked my server but there is no problem in there. What can be the problem? I'm really confused.
    There are lots of people asking for this kind of question but there is no clear answer that I can find.
