I assume you shared the configuration for the local VPN gateway.
On this VPN gateway you need to make sure that you have a route to 192.168.75.5/32 that egresses on ge-0/0/0.0
I believe you have it as you can see the counter for encrypted packets increasing.
Similarly on the remote peer you need to have a route to 192.168.1.187-190 that egresses your untrust interface. Maybe this route is missing.
