SRX routing problem

We are using policy based routing  for to send udp traffic from different route
We have started a TCPdump on cent os server and realize that traffic succesfully arriving to the cent os from expected route
And it is answering it

We put counters to trace udp traffic for 185.9.157.18 and udp answers arrive to the srx from xe-1/0/1 as expected but not go outside from any where on the device

Filter: Bloker2
Counters:
Name                                                Bytes              Packets

and there is no output
no IDS log on screens
when i change tcp and udp traffic routings to the opposite it is working perfectly
Whenever i put to udp traffic to different uplink then main gateway'a L3 port it is stopping


what should be the problem ?
