<DIV>Hi,</DIV>
<DIV> </DIV>
<DIV>I downloaded openswan-2.4.0rc4.tar.gz from openswan.org and then I configured the file ipsec.conf for NULL encryption using esp=NULL. Further, I checked that the NULL encryption is implemented in the code (ESP_NULL), so </DIV>
<DIV> </DIV>
<DIV>1) I had set the value of the flag SUPPORT_ESP_NULL in the file spdb.c as shown below:<BR><BR>#define SUPPORT_ESP_NULL 1<BR></DIV>
<DIV>2) Further, I had set "CONFIG_KLIPS_ENC_CRYPTOAPI=y" in defconfig file.</DIV>
<DIV><BR>However, NULL encryption is not working at all. Could somebody guide me through this problem. I would really appreciate any kind of help.<BR></DIV>
<DIV>Here is the setting of my ipsec.conf file:</DIV>
