Hi Carlito, Thanks for your response. I saw thread created by you about nat44 time out problem. I didn't check end-point dependent mode, but I do some tests on deterministic mode And in this mode, timeouts work correctly and sessions are deleted after their expiration times.
Dear Vpp folks, Based on observation on threads related to nat plugin, it seems the nat plugin project is not live or it has a weak community. what's your opinion? Is it right? Does anyone work on nat already? I appreciate someone who worked or works on nat plugin give us feedback.
