Your company plans to implement an Internet gateway router that is performing NAT. This same gateway will be terminating various IPsec tunnels to other remote sites. Which address type is appropriate

Inside local addresses are the pre-NAT private addresses; by the time the outbound crypto ACL is evaluated, these addresses have already been translated and would not match the packet headers.

On a router performing both NAT and IPsec, outbound traffic from the inside is NAT-translated first - converting inside local (private) addresses to inside global (public) addresses - before the crypto map ACL is evaluated; therefore the ACL defining interesting traffic for the IPsec tunnel must match inside global addresses to correctly select and encrypt the traffic.

Outside local addresses represent destination hosts as seen from inside the network, not the source addresses of traffic originating from inside that the crypto ACL must match.

Outside global addresses represent the actual routable addresses of external destination hosts, not the translated source addresses that the crypto ACL governing interesting traffic must identify.
