Some of the users at my location are accessing the Internet by
bypassing the in-house proxy server. They are just typing the upstream
proxy server IP address and port number in browser and accessing the
Internet. How can I prohibit such activities? My network is on
192.168.7.0 and IP address of upstream proxy server is 195.2.104.7
(take these IP addresses as an example). I can access 195.2.104.0
network from my location. I am using Squid Proxy server on Linux
RH8.Can anyone suggests use of IPTABLES to achieve this?
