Hi all,<br>
<br>
I am using ESP in transport mode between IMS SIP Client and PCSCF ( 3GPP 33.203).<br>
I am running the SIP client on linux kernel using setkey to manage SAs.<br>
When the ESP packets from the PCSCF are fragmented, the linux kernel is not processing it.<br>
I am not able to receive the packet at the application.<br>
<br>
Linux Version: Linux ubuntu 2.6.24<br>
<br>
The following ESP packet is fragmented, but the kernel is not
processing it. I am not receiving the packet at application. If the ESP
packet is not fragmented, it works fine.<br>
