Title: How do i block certain LAN IP from accessing internet?
Post by: jay on May 03, 2006, 08:25:49 AM

Good day,

I would like to block certain lan ip (not ip range) from accessing internet and only allow to access certain websites. Hope somebody can help me on this. I used one of the article in linuxsolved forum to do the internet sharing (http://www.linuxsolved.com/forums/viewtopic.php?p=298#298).

I shall be grateful if somebody can assist me on this.

Thank you.

well that is possible. Use squid and create seperate acl for each client and then set access control for it.

Yes, Ricky pointed out.

You can either use:

1. Proxy

or

2. Pure iptables to filter out.

If, ur filtering out different networks according to their network segments, i.e.:

10.0.0.x
10.0.1.x
well it's still possible

If, ur serious about iptable to help u, u can dig here:
