Can anyone pls help me to understand how traffic flow from One context to another context Asa Firewall 

I have two Context i.e Context A and Context B

I Have a destination behind the context A which need to be reachable from context B.

I have nat policy on Context B that is dynamic nat interface to outside interface but when im initiating the traffic from context B to reach Destination i can see original packet on Context A not the nat Interface Ip of Context B . why im seeing the original packet of context B even im using the Nat policy.

Multi-Context means 2 separate devices, so means there is no internal communication between these devices, they required routing leaks between either common interface or it needs to be routing outside the common routing table.

 

can you provide the example configuration and logs to understand?

 

here is good guide how flows works :
