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? -----Original Message----- From: Wei Ming Long [mailto:[EMAIL PROTECTED] Sent: Wednesday, July 02, 2003 12:59 AM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: RE: [squid-users] question about Forcing proxy. 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 >>> "Jason Brashear" <[EMAIL PROTECTED]> 07/02/03 10:16AM >>> 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 The requested URL could not be retrieved ---------------------------------------------------------------------------- ---- While trying to retrieve the URL: / The following error was encountered: Invalid URL Some aspect of the requested URL is incorrect.

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, -Jason Brashear
