How to limit internet access to just a few websites?

Why not use putty or share your desktop so you just need to work on one computer with a lot of ways to access it? Give each computer ip address that can be remote from a distance. Problem solve?

Some advanced firewalls might be able to limit internet sites, but probably involve a lot of configuration.

I'm thinking that if you are able to access that router then you can go into the configuration settings and you can change things in relation to security and Internet access that way. If you do this though then no one will be able to access the so called sites that you mention. I think that you need to input the sites, their domain names and so forth so that they would be recognised if someone was trying to access them. One way to access the router is if you know the ip address of the router. You can then insert this into the address bar of your Internet browser and this should bring up the configuration for the router. Anyway, I only know this as I sometimes access the configuration of my own router and it has things like access restrictions. Good luck and I hope that you are able to resolve this problem. Andrew

I think if you want to limit internet access then you should use proxy for sites.. I think you can use many software who are really works good for limit internet access.. or you can just going to an internet options to limit your internet access..
