Likely it is only limited by the total number of ports...around 65000. You will likely hit a memory or cpu limitation before though and that will varry greatly from router to router. I know commercial cisco routes have no issues using all the ports on one IP and if that is full move to another.

Thank you for the answer bill001g. Appreciate your help.
Could you also tell me what "4096 ports are reserved" means. Is it that, 4096 ports are reserved for some other applications?
Mostly the low ones are reserved so the nat starts with the high ones and most user ports are high anyway. In most cases the application do not enforce port numbers so you can use almost anything as a source.
