Hi!

What does the above statement mean?

I am trying to nat some traffic but the packet tracer shows that packets get dropped at the NAT rpf-check step.

Hello Lajja1234,

It means that on the way  back  ( the returning traffic) there is no valid NAT for that traffic,

You can post the traffic that you want to allow and the packet tracer, I will then provide you what you need
