[squid-users] Tproxy and WCCP configuration error

I have successfully configured tproxy all the steps. (Patching Centos,
Patching iptables, Building squid).And also WCCP configuration with L4
WCCPv2. When I trying check gre0 tunnel with any packet flow but don't
found any request.

My error showed..............
[root_at_heldas]# tcpdump -i gre0
tcpdump: WARNING: arptype 778 not supported by libpcap - falling back to
cooked socket
tcpdump: verbose output suppressed, use -v or -vv for full protocol
decode
listening on gre0, link-type LINUX_SLL (Linux cooked), capture size 96
bytes
^C
0 packets captured
0 packets received by filter
0 packets dropped by kernel

My iptables script is...........

#/bin/bash
/sbin/iptables -t mangle -N DIVERT
/sbin/iptables -t mangle -A PREROUTING -p tcp -m socket -j DIVERT
/sbin/iptables -t mangle -A DIVERT -j MARK --set-mark 1
/sbin/iptables -t mangle -A DIVERT -j ACCEPT
/sbin/iptables -t mangle -A PREROUTING -p tcp --dport 80 -j TPROXY
--tproxy-mark 0x1/0x1 --on-port 3129

My Physical connectivity structure is ....
