[umer]

Hello EVeryOne I am going to use squid and iptables on same server
my squid work perfect without iptables
but when i use rules in iptables it does not work

should i change anything in config file of squid (for iptable?

Hier is my rules

Chain INPUT (policy DROP)
target prot opt source destination
ACCEPT all -- 192.168.20.0/24 anywhere
ACCEPT all -- anywhere 192.168.20.0/24
ACCEPT tcp -- anywhere anywhere tcp dpt:www

Chain FORWARD (policy DROP)
target prot opt source destination

Chain OUTPUT (policy DROP)
target prot opt source destination
ACCEPT all -- 192.168.20.0/24 anywhere
ACCEPT all -- anywhere 192.168.20.0/24
ACCEPT tcp -- anywhere anywhere tcp spt:www

First try to install Squid server (use up2date squid) and configured by adding following directives to file:

# vi /etc/squid/squid.conf

Then with the help of the following try to modify or try to add the following squid directives:

httpd_accel_host virtual
httpd_accel_port 80
httpd_accel_with_proxy on
httpd_accel_uses_host_header on
acl lan src 192.168.1.1 192.168.2.0/24
http_access allow localhost
http_access allow lan

Here is the complete listing of squid.conf for your reference (grep will remove all comments and sed will remove all empty lines.

# grep -v "^#" /etc/squid/squid.conf | sed -e '/^$/d'

I will suggest to put the proxy server ip address as a gateway then try to connect to the internet,then you need to central server to control how every browser uses proxies to a finer level. Try using a proy.pac file to execute on your proxy server.
