Dear VPP hackers, I need your advice concerning configuring and possibly extremely ending the NAT in VPP.
We are currently using nat44 in endpoint-dependent mode. We are witnessing TCP sessions piling up even though clients close connections gracefully. These lingering sessions are categorised as WAIT-CLOSING by show nat44 summary. After a timeout they are considered CLOSED and could get reaped (lazily). I suspect that this behaviour is actually correct, since the NAT seeing FIN/ACK passing by doesn't imply that the packets were actually delivered. Please confirm. It looks like RST doesn't terminate a NAT session (doesn't put it in WAIT-CLOSING state), are there reasons for that as well? Best, N
