Hi, We are trying to run Squid 3.4.6 with TProxy. Earlier we used to run Squid 2.7.Stable9 in "transparent" mode with a DNAT rule on the router box to redirect traffic. This being our first jibe at Squid3, we have successfully configured "intercept" mode with the router doing a policy-based routing (instead of DNAT). All works quite well! However, when we try to do a TProxy configuration, Squid does not seem to be seeing the traffic at all. Since Squid3 is working in "intercept" we assume that is not the problem. IPTables is configured as follows: *mangle :PREROUTING ACCEPT [0:0] :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :POSTROUTING ACCEPT [0:0] :DIVERT - [0:0] -A PREROUTING -p tcp -m socket -j DIVERT -A PREROUTING -p tcp --dport 80 -j LOG --log-prefix "TProxy: " -A PREROUTING -p tcp --dport 80 -j TPROXY --tproxy-mark 0x1/0x1 --on-port 3129 -A DIVERT -j MARK --set-mark 1 -A DIVERT -j ACCEPT COMMIT The Log option shows similar lines as follows (our IP omitted below): Jul 3 05:15:24 proxy01 kernel: TProxy: IN=eth0 OUT= MAC=00:22:4d:a7:9a:8c:00:15:17:c8:a0:39:08:00 SRC=<test> DST=195.93.85.193 LEN=52 TOS=0x00 PREC=0x00 TTL=1 ID=25176 DF PROTO=TCP SPT=3264 DPT=80 WINDOW=65535 RES=0x00 SYN URGP=0 We also tried both with and without the "IP" commands: ip rule add fwmark 1 lookup 100 ip route add local default dev eth0 table 100 We have searched through Google, mailing lists, Squid Docs, but seems like we are still missing through something. One thing though, a lot of the TProxy examples accompany WCCP or Bridge. Are either of them mandatory in TProxy setup? If not, could someone help us where we are doing things wrong? Thanks in advance for youguidance. Regards HASSAN
