Interesting traffic ACL in GRE?

Hi All! I’m little bit confused, i’m configuring a routed based vpn, GRE tunnel for a ASA and a Router with both Ipsec in my test enviroment. Do a still need a interesting traffic ACL and do i also need to exempt traffic from noNat or Overload, this is needed for a policy based vpn configuration (Anyconnect or site to site)?
