I'm pulling the configs off our old 515 firewalls and putting them on our new ASA 5500's. On the 515, we were NATng everything inside to a public address tied to the outside interface (not the interface address itself). Here is the config for the inside NAT
nat (inside) 1 0.0.0.0 0.0.0.0
global (outside) 1 x.x.x.x
I also have similiar NAT statements on other interfaces on the PIX, all which are similiar as my inside NAT config.
My question is, do I need to enable nat-control on the ASAs to make it behave the same way as my 515s? I'm a little confused as to whether its needed or not?
