RE: [squid-users] question about Forcing proxy.

Thank you all That worked, I configurd SQUID for tranparent Proxy and it is
now working like a champ!
Also do I need to port 443 to squid as well? or will squid get all HTTP
requests being told only to forward port 80?

Now how do I require a user name and password to access the web pages?

Hi Jason,
Did you enable ip_forwarding in your linux kernel.
check by "cat /etc/sys/net/ipv4/ip_forward", if it's 0, then echo "1" >>
/etc/sys/net/ipv4/ip_forwarding.

Do read the doc on transparent proxy.

Cheers
Matthew

One more thing to add..

Also when I ad this line
to my firewall rules:
$IPTABLES -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j
REDIRECT --to-port 3128

I get this in my web browser:

ERROR

While trying to retrieve the URL: /
The following error was encountered:

(squid/2.5.STABLE1)
I have a system running SQUID with two nics.
One Public and one private.
The private issues a Dynamic IP address to the clients on the inside via
DHCP.
What I want to do is force all port 80 443 in bound traffic  to squid so
that
proxy occurs with out having to add a proxy server setting their browser.
Any ideas?
I know that I should be able to do this with IPTABLES.
I am running on RedHat 9.0 Also I hav esquid Guard installed and that seems
to really rock.
Please help!
Thank you,
