Hello,

Can you further elaborate on your question.

Have you configured the NAT and ACL.

Can you run a packet tracer:

Assuming the external interface name is outside and the connection is on port tcp/80;

packet in outside tcp 8.8.8.8 1025 server_public_IP 80

Regards,

Felipe.

Hi Qiu,

If I am understanding you correctly you want to access internal server from behind same interface on it's public ip. If that is the case you could do the following configuration:

Suppose server internal ip is 1.1.1.1 and it's public ip is 2.2.2.2 and server is behind inside interface.

object network obj-1.1.1.1

host 1.1.1.1

exit

object network obj-2.2.2.2

host 2.2.2.2

exit

nat (inside,inside) source dynamic any interface destination static obj-2.2.2.2 obj-1.1.1.1

Hope that helps!
