Kannel and Kwtls

Hello,

  I know it's a bit outside kannel...
I'm using kannel 1.1.3 and kwtls 0.1.3. When i'm using kwtls on port 9203,
I have no problem, i can established a secure session even using
certificate. But, my problem is when I want use kwtls on port 9202, i've
modified kwtls.c and udp.c but the connection always broke after the
server hello and I don't understand. Is there somebody who tried it before
? What can i do ?

thanks for help

Charles
