NAT: Hosts # per overloaded address

[almetcousins]

Hi...

Can some one tell me what is the max recommended amount of hosts (ip's) that you can allocate in one overloaded address in NAT operation.

TIA

Take a look at the following url for an explanation of the maximum number of translations that can be made for each inside global IP address:

NAT sessions are usually limited by the amount of available memory - keep in mind that each translation consumes about 160 bytes of DRAM.
