Which of the following answers defines how the branch NAT config avoids performing NAT for the Enterprise directed traffic but does perform NAT for the Internet - directed traffic?（）
- A、By not enabling NAT on the I Psec tunnel interface
- B、By not enabling NAT on the GRE tunnel interface
- C、By configuring the NAT - referenced ACL to not permit the Enterprise traffic
