<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am using strongswan client for EAP-AKA scenario. Also I am using Strongswan 5.2.2.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am able to establish a call with IPv6 and the virtual IP assigned to client is IPv4. Now when I am initiating a ping of size less than MTU then ping is working fine, I can see IPv4 icmp packets encapsulated within IPv6 ESP packets. When
I am trying to initiate a ping of size greater than MTU then I can see ICMP checksum is incorrect and I am suspecting the way inner ICMP packets are fragmented is incorrect.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Can anyone help me with this issue. If this is a kernel issue then is there any fix for that ? <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have attached the wireshark logs for ping packets of size 1600 bytes (MTU set to 1500 bytes). Key details to decrypt the wireshark is also attached to this mail.
<o:p></o:p></p>

<p class="MsoNormal">Thanks and Regards,<o:p></o:p></p>
