    Block all internet connecton with an excepcion

    We have a SLES sp2 server running, which has internet connection.
    This is in order to send email alerts.
    What I need to do is to block all incoming and outgoing internet traffic (security reason) , except allowing for emails to be send.
    In SUSE firewall you have some nice options, but in my case the internet connection and lan connection are using the same network card.
    So I can't configure internal and external zones.
    I don't want to block anything regarding the internal network.

    Is there a simple solution on how to achieve this?
