Hello Hendrik,

I am facing some issues while implementing Squid + Tproxy and WCCP. There is no problem with squid + Transparent + WCCP.


cache.log as follows...

2009/01/12 08:36:11| clientTryParseRequest: FD 155 (189.50.133.254:1955) Invalid Request 2009/01/12 08:36:18| clientTryParseRequest: FD 114 (189.50.133.254:1956) Invalid Request 2009/01/12 08:36:25| clientTryParseRequest: FD 78 (189.50.133.254:1957) Invalid Request 2009/01/12 08:36:33| clientTryParseRequest: FD 60 (189.50.133.254:1958) Invalid Request 2009/01/12 08:36:40| clientTryParseRequest: FD 60 (189.50.133.254:1959) Invalid Request 2009/01/12 08:36:47| clientTryParseRequest: FD 42 (189.50.133.254:1960) Invalid Request 2009/01/12 08:36:55| clientTryParseRequest: FD 159 (189.50.133.254:1961) Invalid Request 2009/01/12 08:37:02| clientTryParseRequest: FD 77 (189.50.133.254:1962) Invalid Request

access.log as follows...

TCP_DENIED/400 1415 GET / - NONE/- text/html
TCP_DENIED/400 1415 GET / - NONE/- text/html

squid.conf...

http_port 3128 transparent. tcp_outgoing_address is configured.

/usr/local/sbin/iptables -t tproxy -A PREROUTING -i wccp -p tcp -m tcp --dport 80 -j TPROXY --on-port 3128.
.

Squid version : Squid 2.7 Stable 5.

We have configured as squid+tproxy. The squid ip is not displayed and
only the client ip is displayed when we do the proxy test. But after
configuring wccp we find that the server ip is displayed in the proxy
test instead of the client ip.

http_port 3128 transparent tproxy

You should only use one of transparent or tproxy, not both.

transparent for transparent interception (NAT style)

tproxy for TPROXY interception.

Regards
Henrik
