Amos,
Thanks again for your reply.
We have configured squid + Tproxy + WCCP and client ip is redirect to
the web server, but browser shows a connection timeout(110) error and
it takes a long time even to display this error message. The access.log
shows long timestamp value.
forward log shows the request has been forwarded. Squid wotks perfectly
fine when configured as transparent proxy.
We need your valuable advice and if possible can you point out few
areas where are all the possibilities for the problems to arise.
Thanks,
vk

Sorry, we are not using TPROXY but cttporxy 2.6.20-2.0.6, iptables
1.3.8
and linux kernal 2.6.20.21.
Cisco IOS 2800 Ver 12.4 (13b)
WCCP+Tranparent proxy works good. Trproxy without wccp works well by
not
revealing the server ip and only displaying the client ip. But once
the
wccp is enabled with tproxy, the sever ip is revealed instead of the
client ip.
Please scroll down below to check our previous mails.
Any suggestions please.
Other than checking your squid is built with --enable-linux-tproxy,
none
from me sorry.
cttproxy was obsolete and officially unsupported before I ever heard of
it.

Yes. Squid-2.* has no support for TPROXY v4.1+
3.1.0.3 or later is needed. Which is at least an RC beta now, more
stable that pure 3.HEAD alpha code.
Also the squid.conf and configure details have changed.

Hi,
Thanks for the reply. It did help us solve the problem.
But there is a new issue.
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.
We also find that the http request is pathetically slow.

Router Eth0 - connected to lan. Eth1 - connecte to squid.
Have you also configured
* A loopback address on the router, giving it a easily identified
router
ID
* the required GRE/WCCP tunnel interface on the Squid server
* disabled rp_filter on the above GRE/WCCP interface.
* And adjusted the REDIRECT/NAT rules to act on traffic=2

GRE/WCCP interface configured above?

Is there any simple way of configuring WCCP. We have beating round
the
bush all day long to configure wccp.
WCCP as such is configured. But something is missing in the
interception
at the proxy. Most likely the GRE interface mentioned above.

Henrik
