If R4 has a default gateway of R3, you only need to advertise the R3-R4
subnet into OSPF (Either by including it in OSPF, or Redistributing it into
OSPF, depending on the exact wording of the task), if that's allowed.
If R4 doesn't have a default gateway, then yes, NAT is definately the way to
go. Do an overload on R3's interface making all traffic to R4 appear to be
locally originated, and R4 will be able to reply anywhere in the network.
