What is the maximum concurrent NAT/PAT translation number on a PIX 535?

The Firewall Service Module (FWSM) supports 256,000 concurrent NAT and 256,000 concurrent PAT translations.

THX.

Hi,

I don't think Cisco mentions this for PIX, since every connection is translated (NAT 0 is still a transaltion) :)

You should look for the number of connections.

PIX 535

? Cleartext throughput: Up to 1.7 Gbps

? Concurrent connections: 500,000

Keep in mind that for a given Public IP, a PAT can sustain a max number of 4000 private IPs. The higher the number, the lower the performance.

Please rate if this helped.

Daniel
