Provide internet access for servers behind the LTM configured with 2 different route domains (Outside/Inside)

Hello everybody,

Would you please help me provide internet access for one of my servers behind the LTM. I know how to do it without route domains but because of IPS Passthrough design I configured to different route domains. traffic from outbound (route domain outside) to inbound (route domain inside) is working fine but from inside to outside is not working. Any ideas appreciated.
