Hi,
I want to setup a computer with win98, tho don't allow to the users to connect at any IP adress except one, that is for user cannot navigate across the internet, they have to use the connexion only for work purposes, and they need only to connect to one IP.

Its any way to deny acces to all IPs except one (or few IPs), via some kind of proxy installed, or somtehing else?

Thx

You can certainly set up "allowed" and "disallowed" IP addresses in most proxy servers, so that would be the easiest way to do this.

Yes I know that, but all proxies that I saw, allow to specifiy the IPs that you want to disallow, the problem is that I want to do exactly the oposite thing,
specify ONLY which IP i want to allow.

Is possible that? with wingate by example no.

Know you any porxy that can do that?

Thx

How do you access the Internet?  Access lists are part of pretty much every router OS, so if you have a router, you probably already have the capability if you can configure it.  This way you do not have to add anything like a Proxy.

Sample computers?  "normal connection to Internet"?  What exactly are these?

I would install a software firewall program like Zonealarm Pro or Norton firewall, or similar that lets you use something like parental control to prevent access to anything but the IP's you allow. It is password protected so that it is difficult to defeat.

I hope this helps !

you can also try disabling dns, and then use a host file with the ip's that you want to allow. the drawback is if the website changes ip addresses it will be unreachable until you edit the host file
NT
location
C:\WINNT\SYSTEM32\DRIVERS\ETC\hosts
