Identity NAT

Hello,

I have the following NAT statements on Cisco ASA;

1- nat (inside,outside) source static SUBNET1 SUBNET1

For this statement, I have configured a source NAT for SUBNET1 using an IP POOL representing IP range for SUBNET1 as well, so I'm instructing the FG to translate IPs from this subnet to itself. (Please correct me if I'm wrong).

But how to do the same configuration in the other direction? outside to inside? Because in case of configuring destination NAT we won't be able to configure External IPs as Mapped IPs.

2- nat (exif_1,inside) source static SUBNET2 SUBNET2 destination static HOST1 HOST1 no-proxy-arp route-lookup

For this  statement, I'm not sure how to configure it on FG.

Please advise.

Thanks
