Hi Sayful,
I think you have terminated the Vlan 192 in reth interface (reth1.192 which has IP 192.168.2.252/24) ,and for the same vlan you have created another L3 interface vlan.192 ( and assigned an IP in the same network, 192.168.2.3/24).
So, if you want to use reth interfaces, remove vlan unit 192 under interfaces and add the reth1.192 interface under security zone untrust . Then it should work.
If this does not resolve the issue , please provide a simple map of your network .
