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?
Hi,
This is the only solution as private addresses are not routeable on the internet and routers should be configured to drop packets with a src IP in the RFC1918 range.
