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. Possible problems: Missing or incorrect access protocol (should be `http://'' or similar) Missing hostname Illegal double-escape in the URL-Path Illegal character in hostname; underscores are not allowed Your cache administrator is [EMAIL PROTECTED] ---------------------------------------------------------------------------- ---- Generated Wed, 02 Jul 2003 02:13:53 GMT by firewall.hostrocks.com (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, -Jason Brashear
