I have 2 RedHat 7.2 servers, I don't know what's version is it?.. they are Server - A (directly connected to the internet) and Server Server - B. Server - A have 2 NICs with different class of IP addresses, the IP address for eth0 is 198.168.0.1 and the other is 202.152.20.28 and its completed with Squid for managing users to browse the internet, on the Server B and it has only 1 NIC with 198.168.1.1 as its IP Address.. and it also completed with Squid..

The problem is:

I want to control users in the Server - B to browse the Internet thru Server A..but I don't want to applied all users IP Addresses in Server B to the ACL commands in the Squid of the Server A.. I only want to applied the ACL Command of IP Address of Server B on the Squid of Server A.. then let the Squid of Server B control its users from its ACL Commands on it own Squid..when they passed the Server B - ACL commands, the server B will ask the Server A to let them browse the internet.

So the process is:

When the users in the Server B want to browse the Internet, the Server B will check the ACL command on its own Squid .. if they passed the ACL Conditions, the Server B will passed them to the Server A then let them go to the Internet..

Hopefully, you understand what I need.. thanks a lot in advance..
