Hi,
I configured Squid in Tproxy mode and Mangled the request, Now i am
able to see my client public address, but i'm unable to see any
request on squid access log.
seems the request is not forwarded to squid or some thing spoofy..
My iptables rules
-A PREROUTING -p tcp -m socket -j DIVERT
-A PREROUTING -p tcp -m tcp --dport 80 -j TPROXY --on-port 4xx5
--on-ip 10.x.x.x --tproxy-mark 0x1/0x1
-A DIVERT -j MARK --set-xmark 0x1/0xffffffff
-A DIVERT -j ACCEPT
