Cisco IOS Software, 2800 Software (C2800NM-ADVIPSERVICESK9-M), Version 12.4(3f), RELEASE SOFTWARE (fc3)

Есть FreeBSD 4.11(также проверял на FreeBSD 6.1) c прокси squid-2.5.14 c подержкой wccp 1.

ip cisco 192.168.1.248 lan ge0/0
cisco wan ge0/1
ip squid 192.168.1.77

На FreeBSD создаю туннель:
ifconfig gre0
gre0: flags=b151<UP,POINTOPOINT,RUNNING,PROMISC,LINK0,LINK1,MULTICAST> mtu 1476
tunnel inet 192.168.1.77 --> 192.168.1.248
inet 192.168.1.77 --> 10.10.10.10 netmask 0xffffffff

ipfw add 00450 fwd 127.0.0.1,3128 tcp from any to any 80 in recv gre0

в squid.conf прописываю
wccp_router 192.168.1.248
wccp_version 4
httpd_accel_port 80
httpd_accel_host virtual
httpd_accel_with_proxy on
httpd_accel_uses_host_header on

На сisco:
.....
no ip cef
ip wccp version 1
ip wccp web-cache redirect-list 5
access-list 5 deny 192.168.1.77
access-list 5 permit any
.........

no ip unreachables
no ip proxy-arp
ip wccp web-cache redirect out

Делаю на cisco
#show ip wccp web-cache
Global WCCP information:
Router information:
Router Identifier: 1.1.1.1
Protocol Version: 1.0

Service Identifier: web-cache
Number of Cache Engines: 1
Number of routers: 1
Total Packets Redirected: 128
Process: 128
Fast: 0
CEF: 0
Redirect access-list: 5
Total Packets Denied Redirect: 0
Total Packets Unassigned: 0
Group access-list: -none-
Total Messages Denied to Group: 0

#show ip wccp web-cache view
WCCP Routers Informed of:
-none-

WCCP Cache Engines Visible:
192.168.1.77

WCCP Cache Engines NOT Visible:
-none-

в итоге wccp не работает.
на FreeBSD tcpdump -i gre0 ничего не отлавливает.
Не могу понять в чем дело. Настораживает только то, что при выводе
router#show ip interface
нет строчки
Web Cache Redirect is enabled
