I am trying to get TProxy setup and running on a Linux based squid box.

I have compiled a custom kernel with the following options (2.6.28.7)

NETFILTER_TPROXY=y
NETFILTER_XT_MATCH_SOCKET=y
NETFILTER_XT_TARGET_TPROXY=y

I have also installed the latest iptables
root@cache-01:/var/log/squid3# iptables -V
iptables v1.4.3-rc1

And compiled squid 3.1.0.6

Squid Cache: Version 3.1.0.6
configure options: '--prefix=/usr' '--includedir=/include' '--mandir=/share/man' '--infodir=/share/info' '--sysconfdir=/etc' '--localstatedir=/var' '--libexecdir=/lib/squid3' '--disable-maintainer-mode' '--disable-dependency-tracking' '--srcdir=.' '--datadir=/usr/share/squid3' '--sysconfdir=/etc/squid3' '--mandir=/usr/share/man' '--with-cppunit-basedir=/usr' '--enable-inline' '--enable-async-io=32' '--enable-storeio=ufs,aufs,diskd' '--enable-removal-policies=lru,heap' '--enable-delay-pools' '--enable-cache-digests' '--enable-underscores' '--enable-icap-client' '--enable-follow-x-forwarded-for' '--with-filedescriptors=65536' '--with-default-user=proxy' '--enable-linux-netfilter' --with-squid=/tmp/squid-3.1.0.6 --enable-ltdl-convenience

My NAT Rules are as follows

echo 1 > /proc/sys/net/ipv4/ip_forward
/sbin/iptables -t mangle -N DIVERT
/sbin/iptables -t mangle -A DIVERT -j MARK --set-mark 1
/sbin/iptables -t mangle -A DIVERT -j ACCEPT
/sbin/iptables -t mangle -A PREROUTING -p tcp -m socket -j DIVERT
/sbin/iptables -t mangle -A PREROUTING -p tcp --dport 80 -j TPROXY --tproxy-mark 0x1/0x1 --on-port 3129

My Squid config shows

http_port 3128
http_port 3129 tproxy

If I run a dmesg I see it loads the tproxy support

[   15.339298] ip_tables: (C) 2000-2006 Netfilter Core Team
[ 15.458549] NF_TPROXY: Transparent proxy support initialized, version 4.1.0
[   15.458552] NF_TPROXY: Copyright (c) 2006-2007 BalaBit IT Ltd.
[   15.510067] nf_conntrack version 0.5.0 (16384 buckets, 65536 max)

A tcpdump shows http traffic hitting the box but nobody it able to surf.

Any ideas what could be wrong??


Not from what you have said so far. It all looks correct according to current knowledge.

Have you remembered to set the Squid ACLs to permit the local network ranges propery?

Is there any trace in the squid logs? and what exactly are the users seeing?
