[squid-users] Squid -2.6.STABLE13 + WCCP Problem

Greetings all, I am once again returning to you all for some assistance.
 
The following is a desription of my problem, here is a legend
designating the various devices in my network:
WCCP2 Router : 000.111.222.333
Squid Server : 444.555.666.777 ( squid1.austin.network.com
)
 
I have installed Squid -2.6.STABLE13 with WCCPv2 enabled on a CentOS 4.4
server (2.6.9-42.0.10.EL kernel). I have ip_forward enabled, I have
iptables configured to REDIRECT traffic inbound on port 80 to port 3128
the way I've always done it. Nothing appreciable has changed on the
network. I'm convinced that this is an issue with the new
software/config.
 
Thus, I went through the configuration and made the following settings I
gathered were pertinant to WCCP:
 
http_port <444.555.666.777>:3128 transparent
wccp2_router <000.111.222.333>
wccp2_forwarding_method 1 (the WCCP device upstream is a Cisco router)
wccp2_return_method 1 (the WCCP device upstream is a Cisco router)
wccp2_assignment_method 1
wccp2_service standard 0
wccp2_weight 10000
 
I created a GRE tunnel according to instructions on wiki.squid-cache.org
and made all the other settings I figured I needed and started up Squid.
The following was put in the cache.log, among other things:
 
Accepting transparently proxied HTTP connections at <444.555.666.777>,
port 3128, FD 73.
2007/06/10 12:51:16| Accepting ICP messages at 0.0.0.0, port 3130, FD
74.
2007/06/10 12:51:16| WCCP Disabled.
2007/06/10 12:51:16| Accepting WCCPv2 messages on port 2048, FD 75.
2007/06/10 12:51:16| Initialising all WCCPv2 lists
2007/06/10 12:51:16| Ready to serve requests.

However, nothing else happens. In my other Squid/WCCP server I get
messages in the cache.log file showing the WCCP negotiation traffic,
nothing shows on this machine.
 
When I run tcpdump host <wccp2_router's IP> -vv I get the following:

To make things a bit more puzzling we already have one Squid/WCCP server
running here and the box I'm currently trying to get configured and
running used to be the second one of a pair, but the existing one is
running squid-2.5.STABLE3 on a RedHat9 (2.4.20-19.9 custom compiled
kernel) server.
 
If anyone can assist I would appreciate it.
