        modem, simply click the <strong>Remove</strong> button.
        If you also want to access other local machines through
        the same network adapter, click the <strong>Configure</strong>
        button and assign a <strong>fixed IP address</strong> (e.g.
        <strong>192.168.0.1</strong> with subnet mask <strong>255.255.255.0</strong>).
        If you do not take either of these steps, you will
        experience <strong>periodic pauses</strong> while using
        this protocol, because <strong>Windows</strong> will
        periodically halt the network adapter and try to acquire
        for an IP address for it, which also makes the machine
        take significantly longer to boot up.</li>
</ul>

<ul>
    <li>Click the <strong>OK</strong> button to close the <strong>Network
        Configuration</strong> window and confirm to reboot.</li>
</ul>

<ul>
    <li>After the reboot, the protocol is fully functional, but
        you still need to create a dial-up connection to use it.
        See the next section for details.</li>

<h3><a name="Section3"><u>3.</u></a><u> Creating PPP over
Ethernet Dial-up Connections</u></h3>

<p>PPP over Ethernet dial-up connections can be most conveniently
created with the <strong>Dial-up Connection Setup </strong>application
provided with the protocol, which creates dial-up connections
with all the correct settings at the click of a button.</p>

<ul>
    <li><strong>NOTE:</strong> The <strong>Dial-Up Networking</strong>
        folder interferes with the operation of this application
        and prevents successful creation of dial-up connections.
        Thus, if you currently have the <strong>Dial-Up
        Networking</strong> folder <strong>open</strong>, please <strong>close</strong>
        that window before proceeding.</li>
</ul>

<ul>
    <li>Click the <strong>Start</strong> button on the taskbar
        and select <strong>Run...</strong> to bring up the <strong>Run</strong>
        dialog box.</li>
</ul>

<ul>
    <li>Type <strong>RASPPPOE</strong> in the edit field and
        click the <strong>OK</strong> button to run the <strong>Dial-up
        Connection Setup</strong> application.</li>
</ul>

<ul>
    <li>If the application quits with an error message, follow
        the advice it gives.</li>
</ul>

<ul>
    <li>A dialog box comes up with a combo box labeled <strong>Query
        available PPP over Ethernet Services through Adapter:</strong>
        at the top. Select the network adapter your broadband
        modem is connected to from the list. If the protocol is
        only operating on one network adapter, the box will be
        grayed out as there is no choice to make.</li>
</ul>

<ul>
    <li>Generally, it is <strong>recommended</strong> that you
        create a connection for an <strong>adapter</strong>, not
        for a specific service, so that it continues to work even
        if your provider changes the server or service name. To
        do this, simply click the <strong>Create a Dial-up
        Connection for the selected Adapter</strong> button now.
        Shortly afterwards, a shortcut to the new dial-up
        connection named <strong>Connection through </strong><em><strong>Adapter
        Name</strong></em> should show up on your desktop.</li>
</ul>

<ul>
    <li>If you want to create a connection for a <strong>specific
        service</strong>, click the <strong>Query Available
        Services</strong> button. The application will send out a
        query for offered services and display the result in the
        list view below. If an error message is displayed, see <a
        href="#Trouble2">Troubleshooting</a> for help. Otherwise,
        select the desired service and the button below will
        change to <strong>Create a Dial-up Connection for the
        selected Service</strong>. Click the button to create a
        connection for this service. Shortly afterwards, a
        shortcut to the new dial-up connection named <strong>Connection
        to </strong><em><strong>Service Name</strong></em><strong>
        at </strong><em><strong>Access Concentrator</strong></em>
        or <strong>Connection to </strong><em><strong>Access
        Concentrator</strong></em> (if the connection is for the
        default service) should show up on your desktop.</li>
</ul>

<ul>
    <li>After you have created the connection(s) you need, click
        the <strong>Exit</strong> button to quit the application.</li>
</ul>

<ul>
    <li>Double-click the desktop icon for the dial-up connection
        you created.</li>
</ul>

<ul>
    <li>In the <strong>Connect To</strong> window, enter your
        user name and password if your service provider requires
        authentication.</li>
</ul>

<ul>
    <li>Click on the <strong>Connect</strong> button. If all goes
        well, you should be connected to the Internet almost
        instantly. If not, see <a href="#Trouble3">Troubleshooting</a>.</li>

<h3><a name="Section4"><u>4.</u></a><u> Removing the PPP over
Ethernet Protocol</u></h3>

<ul>
    <li><font color="#FF0000"><strong>NOTE:</strong></font> Since
        the removal requires a <strong>reboot</strong> to finish,
        you are advised to save your work and close all running
        applications before proceeding.</li>
</ul>

<ul>
    <li>First, you may want to remove all dial-up connections you
        created for connecting with this protocol. To do so,
        first double-click the <strong>My Computer</strong> icon
        on your desktop. If you are running <strong>Windows ME</strong>,
        double-click the <strong>Control Panel</strong> icon in
        the opened window. Now double-click the <strong>Dial-Up
        Networking</strong> icon in the last opened window. In
        the <strong>Dial-Up Networking</strong> window, right-click
        each of the dial-up connections you created for this
        protocol and select <strong>Delete</strong>. If you had
        created any shortcuts to these dial-up connections on
        your desktop, right-click them and select <strong>Delete</strong>
        as well.</li>
</ul>

<ul>
    <li>Right-click the <strong>Network Neighborhood</strong> (Windows
        98/98SE) or <strong>My Network Places</strong> (Windows
        ME) icon on your desktop and select <strong>Properties</strong>
        to bring up the <strong>Network Configuration</strong>
        window.</li>
</ul>

<ul>
    <li>For each adapter the protocol is operating on, you will
        find <strong>three</strong> bindings in this window:</li>
</ul>

<blockquote>
    <ol>
        <li><strong>NDISWAN -&gt; PPP over Ethernet Miniport</strong>.</li>
        <li><strong>PPP over Ethernet Miniport -&gt; PPP over
            Ethernet Protocol</strong></li>
        <li><strong>PPP over Ethernet Protocol -&gt; </strong><em><strong>Adapter
            Name</strong></em></li>
    </ol>
</blockquote>

<ul>
    <li>Locate all <strong>PPP over Ethernet Protocol -&gt; </strong><em><strong>Adapter
        Name</strong></em> entries in this window, select them
        one by one and click the <strong>Remove</strong> button.
        The other two bindings belonging to this one will be
        automatically removed. If you accidentally remove one of
        the other bindings, no harm is done - you only need to
        remove the other two manually in this case.</li>
</ul>

<ul>
    <li>Once you have removed all protocol instances, click the <strong>OK</strong>
        button to close the <strong>Network Configuration</strong>
        window and confirm to reboot.</li>
</ul>

<ul>
    <li>After the reboot, the protocol is usually completely
        removed from your machine. In some cases, <strong>Windows</strong>
        keeps a copy of the INF file in the <strong>\WINDOWS\INF\OTHER</strong>
        directory, named as <strong>Robert SchlabbachWINPPPOE.INF</strong>.
        You can safely delete this file after removal.</li>
</ul>

<h3><a name="Section5"><u>5.</u></a><u> Advanced Protocol
Features</u></h3>

<p>This section covers the advanced features of the protocol.
Average users should be perfectly happy with the default
settings, although <a href="#Advanced4">specifying the link speed
to display</a> may be of interest. Users having problems with VPN
software might try if <a href="#Advanced2">overriding the MTU
reported by the protocol</a> helps. Users with flat rate Internet
access may be interested in <a href="#Advanced5">making the
connection &quot;always on&quot;</a>. If you are interested in
using the protocol's server capability, please see <a
href="#Advanced7">Enabling the protocol to act as a PPPoE Access
Concentrator</a>.</p>

<p>To bring up the protocol settings for an adapter:</p>

<ul>
    <li>Right-click the <strong>Network Neighborhood</strong> (Windows
        98/98SE) or <strong>My Network Places</strong> (Windows
        ME) icon on your desktop and select <strong>Properties</strong>
        to bring up the <strong>Network Configuration</strong>
        window.</li>
    <li>Locate the <strong>PPP over Ethernet Protocol -&gt; </strong><em><strong>Adapter
        Name</strong></em> entry for the adapter the protocol
        settings of which you wish to modify, select it and click
        the <strong>Properties</strong> button to bring up the
        protocol's settings for this adapter.</li>
    <li>Any changes to the protocol settings require a <strong>reboot</strong>
        to take effect. You will be prompted to reboot when you
        close the <strong>Network Configuration</strong> window
        with the <strong>OK</strong> button after making any
        changes.</li>
</ul>

<p>The <strong>General</strong> tab offers the following settings:</p>

<blockquote>
    <h4><a name="Advanced1"><u>5.1</u></a><u> Limit TCP MSS
    Maximum Segment Size (MSS) Option</u></h4>
    <p>When using <strong>Internet Connection Sharing</strong>,
    the client machines are completely unaware of the packet size
    restrictions imposed by the nature of <strong>PPP over
    Ethernet</strong> (in contrast to e.g. <strong>modem</strong>
    or <strong>ISDN</strong> connections, which allow passing
    arbitrarily sized packets). Typically, a client assumes that
    packets of up to <strong>1500</strong> bytes can be passed
    and thus indicates a <strong>Maximum Segment Size</strong> of
    <strong>1460</strong> bytes (1500 bytes minus 40 bytes for
    the TCP and IP headers) when opening a <strong>TCP</strong>
    session, resulting in either side of the connection sending
