It works and the phase 1 is not put down by Charon but compatibility wise it is not the optimal solution I guess.</div><div>Another solution would be to allow Charon to do nothing after 4 re-transmissions or maybe check the use time of phase 2 or launch some DPD.<br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div>Any ideas on this problem ?<br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div>Thank you.<br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div>Jean-François Hren<br data-mce-bogus="1"></div></div></body></html>
