Hairpin NAT on FirePower / FMC

[Xividar]

Hi Guys,

Does FirePower with FMC support hairpin NAT? I need 2 servers to be able to contact another internal server, but by using it's publicly NAT'd address.

Thanks for your help.

Hi @Sheraz.Salim thanks for that link, again, I saw that one, but it's not exactly what I'm after. I am going from Inside to Outside, no DMZ involved.

Xividar could you please explain in detail what you want to acheive please.

The scenario is.

Server A which lives in my INSIDE zone has 1:1 NAT, private to public IP address.

Server B and C, which both live in my INSIDE zone, and are both private on the Inside, need to take to the public address of Server A.

Thank you @Sheraz.Salim

for this to work do they need to be on same port as using by server A. or the server B,C using the different ports?

If the answer is they SERVER A-B-C will use a different port in that case it is due able with using a Single Public IP address.
