Forcing proxy on IPCOP

Hi,

is there a way to force clients using proxy on ipcop?

You need to block direct IP access for all clients using iptables. That way, clients will have to specify the IPCOP as their proxy server in order to access the internet.

Hi,
thanks for answering me.
Could you please explain me how to do that? I'm new on linux.

Thanks in advance

You need to make changes to your rc.local file which is located in the following directory /etc/rc.d/

Add the following commands after the line containing "#!/bin/sh"
[code:1]
# Flush Custom Input Rules
/sbin/iptables -F CUSTOMINPUT
/sbin/iptables -F CUSTOMFORWARD

#bar access for all IPs
/sbin/iptables -A CUSTOMFORWARD -i $GREEN_DEV -s 0/0 -o $RED_DEV -j DROP
[/code:1]

The above rules simply block direct access for all clients.

After editing rc.local, you can run it by typing "/etc/rc.d/rc.local".

Hi,
thanks for helping me.
I followed what you suggest but when I try to run the command, this warning appear:

root@ipcop:~ # /etc/rc.d/rc.local
Warning: wierd character in interface `-s' (No aliases, :, ! or *).
Bad argument `0/0'
Try `iptables -h' or 'iptables --help' for more information

Replace [code:1]/sbin/iptables -A CUSTOMFORWARD -i $GREEN_DEV -s 0/0 -o $RED_DEV -j DROP[/code:1]
with:
[code:1]/sbin/iptables -A CUSTOMFORWARD -i $GREEN_DEV -o $RED_DEV -j DROP[/code:1]

Also is your RED interface a modem or a network Card?
