Hello,
Due to IPv4 exhaustion, I'm forced to do NAT to my customers can access Internet. I'll have to NAT over 4000 users with 1000 public IPs. Each user can generate over 20 different flows and traffic generated for this users would be over 600 Mbps. What device (router or catalyst) could support this amount of NATs without loss of performance and avoiding to increase too many its CPU?
Thanks in advance.
