Dump missed IP blocks for mudfish item
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Sometimes the technician of mudfish asks you to do the packet dump to get
the missed IP blocks if the mudfish item doesn't work properly.  Then please
try to do as follows:

1. Disable :ref:`Full VPN mode` first.

2. Run `Wireshark`_ and start the packet
   dump.  However please perform a dump for the network interface which
   connects with your ISP.  Please don't dump TAP-Win32 adapter v9 because
   we're looking for missed IP blocked.

3. Please make sure that your items are enabled and run the mudfish launcher. 
   And please wait until your configuration is applied.

4. Progress your steps until the problem is reproduced while Wireshark is
   doing the packet dump.

5. When it's reproduced, stop to capture and save to the file.

6. Sends the packet dump file to support@loxch.com
