Network Object NAT vs NAT

[Alex-Pr]

Hi Everyone,

I'm trying to understand if there is a difference between the following two ways to do NAT and if there is any performance difference

object network VLAN-Inside
nat (VLAN10,OUT-to-Internet) dynamic pat-pool Internet-NAT-POOL round-robin

nat (VLAN10,OUT-to-Internet) after-auto source dynamic VLAN-Inside pat-pool Internet-NAT-POOL round-robin

Essentially I am trying to do NAT for a specific VLAN where the outside IP address does round robin from a pool.   Both methods seems to work but I don't know if one works better then the other or can handle more traffic.

Thanks

Alex.

Hello @Alex-Pr, 

Based on your query, there is no performance difference between the NAT configurations, the only thing that you need to keep in mind is the order the are going to be checked by the ASA.

Other than that, they are the same in performance, here is the link for reference.
