Hi,

That question really depends....The answer is very simple thou, the amount of xlates is not limited. What really limits yourself is either PAT (Which allows 64000 xlates for each IP you use to do PAT) or the amount of connections.

As far as Static NATs go, there is no limit. You can create as much as you want, but eventually doing a sum of all the resources  (inspections, ACLs, QoS etc) will increase the use of the memory.

So, bottom line, you will not get an error that says, static NAT cannot be created.... you will get eventually an error related to memory.

Hi Maykol,

thank you for your response,  I undestand that the static NAT is proportional to a memory of the device,

do you have any document of cisco that especific the amount of resourses that used one static nat on the ASA,

I need select one box that can comply the requirements for one implemetation,

thaks,

Hi Angel,

Well that is a very valid question. Cisco have their Sales engineers and Account managers. If you give them the specific amount of hosts/throughput/resources to use, they will be able to provide more accurate data depending on a deep analisys of your needs.

Hope this helps.
