Hi all. I'm Brazilian, so sorry my bad english. =) I'm looking for a installation manual, with _ALL_ the steps necessary to install the tproxy patch. I found this link, but isn't working. http://fuzzylab00net.blog.dada.net/post/413913/Squid-2.6-+-tproxy-+-bridge-+... I'm trying build an linux box with 2 nic's, in a bridge setup. I have an "real" IP in my bridge interface (189.x.x.x). I have built a lot of kernels with a lot of tproxy's patches. Here is the kernel output: # cat /var/log/dmesg | grep -i tproxy IP_TPROXY: Transparent proxy support initialized, version 4.0.0 IP_TPROXY: Copyright (c) 2002-2007 BalaBit IT Ltd. I have used the file tproxy-4.0.3-2.6.22.tgz to patch my kernel (2.6.22-gentoo-r10). The same patch I've used to compile my iptables-1.3.8. My squid is compiled with the patch too, and my squid.conf is configured: http_port 3128 tproxy transparent tcp_outgoing_address 189.x.x.x My kernel is also configured: net.ipv4.ip_nonlocal_bind = 1 net.ipv4.ip_forward = 1 My ebtables and iptables rules: ebtables -t broute -A BROUTING -p IPv4 --ip-protocol 6 --ip-destination-port 80 -j redirect --redirect-target ACCEPT iptables -t tproxy -A PREROUTING -i br0 -p tcp --dport 80 -j TPROXY --on-port 3128 What I do wrong ? Thanks! Best Regards, Eduardo Schoedler.
