Advice static route "problem"

Hello everyone
I have a some problem with “static route”
My project to connect pptp server between server and client .
Now i applied all configuration from server like pool&pptp server&profile ppp& …etc all are good
In client routerboard applied pptp client with all config. and the status is “connected” .
with client rb need to apply static route to connect with private network from server like for example 192.168.1.0/24 subnet .
noticed that the private network from server created with bridge (two ether but the same subnet) to distribute two ether !
The bridge network don’t have Nat from firewall .
When i applied static route from client vpn and writes (dst address :192.168.1.0/24 and ,gateway : gateway of pptp server (vpn)) at the end apply .
At the end i tested ping from client rb to private network (server) i see timeout ??
whats the problem i have ?
Noticed that i can ping from client to server but the ether in server have private ip address with “nat” without bridge .. i can ping from client rb to private network (server) so i applied in client static route (dst address x.x.x.0/24, gateway : gateway of pptp server ).
regards
