Local route

Hello
We have this network
Users in rb750 side get ip from rb450 side and server in rb750 get ip from rb450side
We use eoip tunnel and bridge it with port in each side
But we have problem is rb750 side
Problem is : when a user want to ping server in rb750 side ping time is about 30ms
Because request go to rb450side and return because of gateway
So i want to how can do it ??if user in rb750 side want to ping server in rb750 side ping request reply just from this side
