+WinDivert sometimes captures outbound or loopback packets before the

+For outbound packets, this occurs when <i>checksum offloading</i> is enabled,

 They are
 <ul>
 <li><i>Injecting inbound ICMP/ICMPv6 messages</i>:
-    For some ICMP/ICMPv6 messages, inbound injection does not work.
-    An error will be returned and the packet will be lost.
-    The work-around is to inject inbound ICMP messages as <tt>outbound</tt>.
+    Calling <a href="#divert_send"><tt>WinDivertSend()</tt></a> will fail with
+    an error for certain types of inbound ICMP/ICMPv6 messages.
+    This is probably because the Windows TCP/IP stack does not handle
+    such messages.
+    Such errors are harmless and can be ignored.
     </li>
 <li><i>The forward layer does not interact well with the Windows NAT</i>:
     It is not possible to block packets pre-NAT with WinDivert.
     As a general principle, you should not try and mix WinDivert at the
     forward layer with the Windows NAT implementation.

+<li><i>Re-injecting unmodified packets can lead to infinite loops</i>:
+    If two or more Windows Filtering Platform (WFP) callout drivers
+    (including WinDivert applications) block and inject unmodified copies of
+    packets then this can lead to an infinite loop.
+    This appears to be caused by a design flaw of WFP.

+<li><i>WinDivert can cause packets to be out-of-order</i>:
+    Simply running the <tt>passthru.exe</tt> sample program can cause
+    packets to become out-of-order.
+    This is not a bug, since there is no requirement for packets to
+    remain in-order.
