@Patrik Nechajev That will work. This example below will translate the host in the object ORIGINAL-SRC to the host in the object TRANSLATED-SRC.
nat (INSIDE,OUTSIDE) source static ORIGINAL-SRC TRANSLATED-SRC destination static PARTNER PARTNER
Replace interface names with your real names and use network objects. Create additional NAT rules for additional objects.
Your VPN crypto ACL will need to reference the TRANSLATED-SRC network/host instead of the real network.
