a unique (randomly generated) identifier in the operating system. It is almost not
possible that two identifiers were identical.
To avoid setting up new interfaces and changing traffic rules, you can assign new
identifiers to original interfaces in the winroute.cfg configuration file.
7. Stop WinRoute Firewall Engine.
8. Use a plaintext editor (e.g. Notepad) to open the winroute.cfg configuration file.
Go to the following section:
<list name="Interfaces">
Scan this section for the original adapter. Find an identifier for a new interface in
the new adapter’s log and copy it to the original adapter. Remove the new interface’s
log.
Example: Name of the local network interface is LAN . This network connection is
labeled as Local Area Connection in the new operating system. Now, the following
data can be found in the Interfaces section (only the essential parts are listed):
<listitem>
<variable name="Id">
\DEVICE\{7AC918EE-3B85-5A0E-8819-CBA57D4E11C7}
</variable>
<variable name="Name">LAN</variable>
...
</listitem>
<listitem>
<variable name="Id">
\DEVICE\{6BF377FB-3B85-4180-95E1-EAD57D5A60A1}
</variable>
<variable name="Name">Local Area Connection</variable>
...
</listitem>
Copy the Local Area Connection interface’s identifier into the LAN interface. Re-
move the data for Local Area Connection (a relevant listitem section).
When all these changes are performed, the data in the configuration file relating to
interface connected to the local network will be as follows:
<listitem>
<variable name="Id">
\DEVICE\{6BF377FB-3B85-4180-95E1-EAD57D5A60A1}
</variable>
