put the nat rule in manual nat.
nat(inside2,outside) after-auto source static DSM-OVPN interface
create the ACL on both direction from inside zone to outside zone where inside zone network will be your DMS-OVPN to any-ipv4 outsidezone.
another rule from outsidezone to insidezone where anyipv4 outside to DSM-OVPN in insidezone.
