asa with firepower vs twice nat

[elkhattabiyassine]

i neet to replace my asa 5515 with asa5516x with firepower. i'm using nat on asa connected outside  to peplink and a have other nat configured on ISP router so i  need to know if the twice nat (1st asa and 2nd on ISP router) can creat any trouble for the IPS fonctions?

Hi,

There should be no problems with IPS functions if the firepower is configured to just look at the traffic moving through the firewall.The firepower should just be looking at the traffic and not doing any modifications.

Thanks
