Queue tree oid not reporting well

Hello guys,

i have the scenario attached in the picture

. I realize right now that the server only can get the oid information from R1 when i am monitoring from one pc next to the server. Server is trying to get oid from bytes on queue tree. When i close the conection between mi pc and the server it stop receiving the oid.

The R2 is nating to his public ip and the trap-target is the ip of the server. Any idea?

No one?

Also i just realice that when is a parent, you can’t get the snmp traps. I am right?
