NAT: Hosts # per overloaded address

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

Re: NAT: Hosts # per overloaded address

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.
