DNAT / SNAT

Hi

Consider I got static NAT for a host on ASA, then traffic from outside to inside is DNAT and traffic inside to outside is SNAT.

Is the above correct

Thanks

Yes, you are right.

Example:

static (inside,outside) 200.1.1.1 10.1.1.1 netmask 255.255.255.255

Outbound traffic from inside to outside, 10.1.1.1 will be NATed to 200.1.1.1

Inbound traffic from outside to inside towards 200.1.1.1 will be NATed back to 10.1.1.1
