Hello Br. Mohammed,
what you need to enable on your ASA are:
1) An nat-exemption for the server IP-address or subnet belong to server that residing in another country i.e. nat-exemption between inside to outside interface of your ASA.
2) If you have enable split-tunnel, then be sure add the remote-MPLS's subnet in the split-tunnel ACL.
3) Advertise remote-access-users' vpn-dhcp pool address on site MPLS-router wherever your ASA is located, so that other MPLS sites would know where to send that traffic is back.
4) Last but not least be sure to add a static route on your ASA to push remote-MPLS's subnet to inside address on your routing device a switch or router.
Hope that helps.
Thanks
Rizwan Rafeek.
