Hi All,
 
I have made one application which works on IPsec on transport mode with 3des/NULL encryption. when I run it with NULL encryption it SA does not estiblish. Then I tried adding manually using setkey command. But i was not successful. I guess my linux kernel is not supporting NULL encryption. can anyone let me know how to debug it? please let me know if anymore info required.
 
Thanks,
Harendra
