Hi, Squid + Tproxy + Bridge Setup on latest kernel - version 2.6.34 I had followed all the steps that had given in the http://wiki.squid-cache.org/Features/Tproxy4 Kernel - 2.6.34 iptable - 1.4.8 ebtable - 2.0.9-1 But clients were unable to browse and no errors in cache.log. Error - Network Unreachable. The error had returned by browser not squid proxy. Workaround :- After adding the following rules, clients are able to browse. # ip rule add dev <device name> fwmark 1 lookup 100 example # ip rule add dev eth0 fwmark 1 lookup 100 NOTE : Repeat the above for each interface except " lo " Source - https://lists.balabit.hu/pipermail/tproxy/2010-January/001212.html Based on the above source this issue had identified on kernel version - 2.6.32. But still not yet fixed. I have CC ed this mail to netfilter mailing lists also. Hope this helps Thanks, Senthil
