Hi,
<br>
<br>Then of course because they're each behind NAT the one TS being dynamic, they will propose different, non intersecting ones for that one.
<br>

Hi Manfred,
<br>
<br>If the peer is strongswqn: Initiate with --child x, not --ike x
<br>
<br>Otherwise: client problem, it sends no TSi or TSr.
<br>
<br>Kind regards
