Try putting in your squid.conf Http_port 127.0.0.1:3128 transparent tproxy Http_port 10.30.17.45:3128 transparent tproxy ----- Original Message ----- From: Brian Møller To: tproxy@lists.balabit.hu Sent: Thursday, February 14, 2008 2:59 PM Subject: [tproxy] Tproxy and squid Hello there I'm in the process of setting up a filtering bridge for my work. I want to use Squid via url_redirect-option to do the filtering. I want to se the source ip of the clients on the webservers because of som logging isues and because the clients come from different subnets and stuff like that I cant do anything against. I'm a little confused when it comes to the versions of tproxy / cttproxy that I should use. From what I can read squid doesn't support tproxy4 so i have to use cttproxy. Am I correct in that assumption? If I'm i have a question: I have compiled my kernel (2.6.20) with this patch-set: http://www.balabit.com/downloads/files/tproxy/obsolete/linux-2.6/cttproxy-2.... And also IPTables 1.3.8 with the same patch-set After that I have compiled squid-2.6.STABLE18 --enable-linux-tproxy after copy'ing one or two .h-files to the right directory. My squid.conf can be seen in the bottom of this email. The bridge is working, traffic is flowing as it should, and the traffic is redirected nicely after running this command: /usr/local/sbin/iptables -t tproxy -A PREROUTING -p tcp -m tcp --dport 80 -j TPROXY --on-port 3128 But now it is the IP of the proxy that gets into the logs of the webservers. Have I missed something or might there be /Brian access_log /var/log/squid/access.log squid acl CONNECT method CONNECT acl QUERY urlpath_regex cgi-bin \? acl SSL_ports port 443 acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 21 # ftp acl Safe_ports port 210 # wais acl Safe_ports port 280 # http-mgmt acl Safe_ports port 443 # https acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 70 # gopher acl Safe_ports port 777 # multiling http acl Safe_ports port 80 # http acl all src 0.0.0.0/0.0.0.0 acl apache rep_header Server ^Apache acl localhost src 127.0.0.1/255.255.255.255 acl manager proto cache_object acl our_networks src 192.168.0.0/16 10.0.0.0/8 acl to_localhost dst 127.0.0.0/8 broken_vary_encoding allow apache cache deny QUERY cache_dir null /null cache_log /var/log/squid/cache.log cache_mem 256 MB cache_store_log none coredump_dir /var/log/squid/cache dns_nameservers 10.30.17.73 10.30.17.71 forwarded_for off hierarchy_stoplist cgi-bin ? http_access allow manager localhost http_access allow our_networks http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access deny all http_access deny manager http_port 3128 transparent tproxy icp_access allow all logfile_rotate 10 refresh_pattern . 0 20% 4320 refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 tcp_outgoing_address 10.30.17.45 url_rewrite_children 30 url_rewrite_program /usr/bin/squidGuard via off ------------------------------------------------------------------------------ _______________________________________________ tproxy mailing list tproxy@lists.balabit.hu https://lists.balabit.hu/mailman/listinfo/tproxy
