[squid-users] squid 2.6STABLE9 WCCPv2 CISCO 2600 w/bad recv_id 00000000

Hi,

I am experiencing
the following problem: Squid does not get any I_SEE_YOU messages and the
router prints out "Here_I_Am packet from 192.168.3.20 w/bad rcv_id 0000000"

Here is the setup and what is happening in more detail:

SQUID BOX
========
IP: 192.168.3.20

Squid 2.6STABLE9, kernel 2.4.32 or 2.6.16, for now the kernel version does not
seem to matter.
For now I use one squid and one router. But once I get this to work, I plan on
using 2 routers and most likely a second squid. Thus the dynamic
configuration.

squid.conf wccp2 settings:

wccp2_router 192.168.3.21
wccp2_forwarding_method 1
wccp2_return_method 1
wccp2_assignment_method 1
wccp2_service dynamic 97 password=exPAS12
wccp2_service_info 97 protocol=tcp flags=src_ip_hash,ports_source priority=240
ports=80
wccp2_weight 10000

STARTING SQUID
============
If I start squid I get the following output on the CISCO:
23:30:08: WCCP-EVNT:D97: Web Cache 192.168.3.20 added
23:30:18: WCCP-EVNT:D97: Built new router view: 1 routers, 1 usable web
caches, change # 00000030

if I restart squid I get the following on CISCO:
23:31:03: WCCP-EVNT:D97: Here_I_Am packet from 192.168.3.20 w/bad rcv_id
0000000

eventually, I get this:
23:50:06: WCCP-EVNT:D97: Redirect_Assignment packet from 192.168.3.20 fails
source check

I do not get any I_SEE_YOU messages in squid's cache.log

The only wccp2 related messages are :
2007/02/08 11:14:22| WCCP Disabled.
2007/02/08 11:14:22| Accepting WCCPv2 messages on port 2048, FD 48.
2007/02/08 11:14:22| Initialising all WCCPv2 lists

TCPDUMP
======
in order to be sure that udp packets are coming through, I captured the
traffic while starting squid

# tcpdump -X -s 1600 -n -i any -p port 2048 &
# squid

if I view this (tcpdump -w dump -X -s 1600 -n -i any -p port 2048) in
ethereal, I can see that "Here I am" and "I see you" messages are sent back
and forth. I can email you the dump, the mailing list does not permit
attachments.

What did I do wrong or miss?

Any pointers are more than appreciated.

Thank you!

Regards,
Martin
