NAT-NVI: translation failed (A) dropping packet
We have configured NAT translation in order to access remotely an application running in port TCP 2000. The application times out and when we run a debug it shows us: "NAT-NVI: translation failed (A), dropping packet s=220.127.116.11 d=18.104.22.168. Can somebody help us diagnose this?
Looks like you are using skinny port for your application; skinny traffic inspection is enable by default for 12.4T code, I am not sure if your IOS has that feature enabled by default. You can disable it using "no ip nat service skinny tcp port 2000".
