How much NAT and Access Rules are allowed on a Cisco ASA 5505?

[Florian Ostkamp]

Hello,

did somebody know where I can find how much NAT and Access Rules on a Cisco ASA 5505 are allowed?

I think there are enough possible but I want to be shure for a Project, what I plan.

Thanks a lot!

Best regards,

Florian

I've never seen hard numbers. You may want to spec your firewall off of the connections, connections/sec, and Inspection Throughput numbers.

Hope it helps.

Hello Collin,

the throughput and Connections per second and so on is not the Problem. But I have to migrate a solution where for each customer a own NAT Rule exists. Now they have about 250 customer... so I Need at least more than 500 possible NAT Rules.

Thanks,

Florian

Hi,

I think the most important question here would be the Code Version.

As Colin pointed out there is no hard limit on the ASA device but it depends on the memory usage on the ASA device.
