greetings!!!

i would like to raise this question with regards to ip nat translation, let say i have a 2000 users using a private ip's and a public ip of /24 question is how many ip from public to translate the 2000 users using a private ip.

Theoretically, PAT(one public IP address) can support up to about 64500 transition depending on different port, but, suggestion is using NAT and PAT synchronously in the configuration.

does single public work on a 2000 clients?how about the router's performance what will be the necessary memory to support the nat translation

hi,

if you have one C class public ip addresses, I suggest you:

1. several public ip addresses will be used to one to one map with VIP SERVER.

2. mostly public ip addresses will be in a nat pool and be used to transition.

3. one public ip address is used to PAT. as soon as the addresses in the nat pool are exhausted, PAT "comes on".
