We are using 1841 router as internet connectivity router. Simple and straight configuration one overload NAT to access internet (Serial 0/0/0 outside to ISP , and fastethernet 0/0 as inside ) and internal users use a private IP range. We need to limit internet access of users only to 2/3 websites and block all other websites, can we implement this on router ?
The best way to make it is to get the ip addresses of the sites you want to be access from inside and create ACL on inside interface to allow only this ip addresses.
