Where can I position the firewall?&lt;BR /&gt; 2. Each Service has to get their own virtual system. What will be the deployment method? Virtual system administrator is only allowed to see its own traffic. They currently have 3 services but it will expand up to 20 services. Physical ports cannot assign to each service. L2 deployment is what they ask for.&lt;BR /&gt; 3. Active/passive has to be there in order to ensure the redundancy. How will be the session synchronization, when one virtual system fails what will happen?&lt;BR /&gt; 4. If I need to deploy the firewall with all features mentioned above will it be possible to deploy in L2 mode?&lt;/SPAN&gt;&lt;/P&gt;&lt;P class="MsoListParagraphCxSpMiddle"&gt;&lt;SPAN&gt; &lt;/SPAN&gt;&lt;/P&gt;&lt;P class="MsoListParagraphCxSpMiddle"&gt;&lt;SPAN&gt; &lt;/SPAN&gt;&lt;/P&gt;&lt;P class="MsoListParagraphCxSpMiddle"&gt;&lt;SPAN&gt;Please someone help me on this matter.. ..&lt;/SPAN&gt;&lt;/P&gt;&lt;P class="MsoListParagraphCxSpMiddle"&gt;&lt;SPAN&gt;Thanks.&lt;/SPAN&gt;&lt;/P&gt;&lt;P class="MsoListParagraphCxSpLast"&gt;&lt;SPAN&gt; &lt;/SPAN&gt;&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
