We have recently leased an internet connection in our office which comes from the service provider as radio link and BW is 2M. I have clients more than 60 that will share the connection and access internet. I have configured a Cisco 2600 router as below:

So far I have read regard NAT it degrades performance as it need to translate every data packet comes from the source and goes to internet.
So a question comes in my mind is there any other way how I can share this connection among users with private ip address? Or NAT is the only method to share internet connection among users with private ip addresses?
If possible how?
