[squid-users] Squid 3.1.0.3 WCCP2 not announcing itself to router?

I had a WCCP2 configuration (using a gre tunnel) working with Squid 3.0
+ sslBump patches, but would like to move up to Squid 3.1 to resolve
some quirks.

Here is the wccp configuration I was using with Squid 3.0:
wccp2_router 10.10.10.1
wccp2_address 10.10.10.250
wccp2_service dynamic 80
wccp2_service_info 80 protocol=tcp flags=dst_ip_hash priority=240
ports=80,443

When Squid is running, the UDP socket is visible:
webcache# sockstat | grep squid
squid squid 25857 6 udp4 *:50592 *:*
squid squid 25857 12 tcp4 *:3128 *:*
squid squid 25857 13 udp4 10.10.10.250:2048 10.10.10.1:2048
squid squid 25855 5 dgram -> /var/run/log

I have setup a packet trace to capture UDP port 2048 packets and
restarted Squid, but I never see any traffic pass through port 2048 (I
would at least expect to see the WCCP "here I am" packet). This
correlates to the WCCP status on the Cisco router that reports 0 cache
engines are using service identifier 80.

I've set debugging_options to 80,5 and this is all that is logged to
cache.log:

I've built Squid 3.1.0.3 under FreeBSD using this configuration:
./configure --with-default-user=squid --bindir=/usr/local/sbin

Any hints?
