[squid-users] Squid/WCCP/Cisco Problem

Hi:

We have the following setup:

        Solaris 8
        Squid 2.5 Stable 4
        IP Filter 3.4.33 pre 2

IP filter is installed with the following ipnat.conf configuration:

        rdr ge0 0.0.0.0/0 port 80 -> 160.91.210.20 port 3128

Squid was configured with:

        --enable-ipf-transparent --enable-wccp

The related squid.conf entries are:

        # httpd_accel_port 80 (Default)
        httpd_accel_host virtual
        httpd_accel_with_proxy on
        httpd_accel_uses_host_header on

        wccp_router 160.91.210.1
        wccp_version 2

Our networking group has configured our Cisco router to do WCCP V2 with
L2 redirection. Due to the lack of a Solaris GRE module and for
performance reasons, we want to use L2 redirection at the router.

I have tested IP Filter without WCCP, and it works as expected with
Squid. When we turned on WCCP, the router does not acknowledge the
Squid server. Our network people have turned on debugging on the router
and got this information:

        Jan 15 07:11:16: WCCP-EVNT:???: Unknown msg_type 7
        on Vlan14 from 160.91.210.20

They then put a sniffer on the network and they see the following packet
coming from the Squid server every 10 seconds:

        00 00 00 07 00 00 00 02 00 00 00 00 ... 00 00 00 00

They say that the 07 should be a 10 for the "Here I Am" message. Is
this correct? Also, they think the "00 00 00 02" should probably be "00
00 02 00", if that's suppose to be WCCP V2.

If we can get the handshaking going, I believe we have WCCP working with
L2 redirection. I don't know if this is a Squid configuration issue or
a protocol problem. Can anyone help us with this?

Thanks for your help,
