    Here's a good article you may find useful: Bridge versus Router Mode Differences, Advantages and Applications.

    Basically, bridge mode set your router's networking to Layer 2:
    Bridges operate at the Data Link Layer (level 2) and do not understand anything about any communications protocol other than the physical medium (MAC), which is typically an Ethernet.
    In other words, what goes in goes out and vice-versa. No IP foot print or coloring.

    Regards.

    P.S.: another way to access your router set in bridge mode would be to create a VLAN and the proper route on the router itself. This would be possible only if the router's firmware allows that functionality (for instance Tomato and DD-WRT do). Another way would be to enable your ethernet interface and setting manually as described in post #5.

    I have been provided with a username and password for authentication to my ISP server.
    pppoeconf uses the pap/chap protocols to achieve this from /etc/ppp/chap-secrets and etc/ppp/pap-secrets.

    If I configure manually and not use bridge(ppp)how do I achieve this.
    I edit the interface eth0 in /etc/network/interfaces and put the interface to static and put in the details.
    Get DNS from etc/resolv.conf .
    If I am not using ppp where do I edit my username and password?
    Also if I will use a private ip like 192.xxx.xxx.xxx how do I setup NAT or is it already configured?
