I successfully configure 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 ........ 
Internet cloud to Cisco core router to Juniper firewall to Distributed
Cisco router to Core Cisco switch to TPROXY  

Please give me a solution ...
