You mean for other routers, ervery 32 private IP addresses will be NATed to one public IP address, and for each private IP address, is could get 2048 ports, and which mean for a specific private user, it could establish sessiones with as most as 2048 different servers. And so that for 4,000 users, it requires 4000/32=125 public IP addresses.

If I'm right, I think you might try the nat session-limit, which allows the router to limit the session for each user.

Hello,
What do you mean not support the port range?
Can you please specify your question more detailedly?
As my understanding, you are going to configure NAT about 4,000 users on the router, and you don't know the configuring steps. Am I right?

Under NAT instance port-range is unable to configure in M2H, as we have configured in other boxes with port-range 2048, which will support 1:32 NATsessions. In this scenario easy to identify how many Public IP's required for 4000 users.
