i put squid on debug section: 89 to follow tproxy and 17 to see what is
going on inside other stuff and i found out this:

section 89 fine not showing anything about using the client ip as
192.168.102.100 :

2012/01/06 04:23:54.072| IpIntercept.cc(381) NatLookup: address BEGIN:
me= 212.179.154.226:80, client= 212.179.154.226:80, dst=
192.168.102.100:1063, peer= 192.168.102.100:1063
2012/01/06 04:23:54.074| IpIntercept.cc(166) NetfilterTransparent:
address TPROXY: me= 212.179.154.226:80, client= 192.168.102.100

section 17 show abnormail thing:
(the outgoing address to the server is the client address and not one of
the server address)

2012/01/06 04:28:36.782| store_client::copy:
7DEA6A0583B90AB461F576C6AEE4AA50, from 0, for length 4096, cb 1, cbdata
0x882b5b8
2012/01/06 04:28:36.783| storeClientCopy2: 7DEA6A0583B90AB461F576C6AEE4AA50
2012/01/06 04:28:36.784| store_client::doCopy: Waiting for more
2012/01/06 04:28:36.785| FwdState::start() 'http://link
2012/01/06 04:28:36.787| fwdStartComplete: http://link
2012/01/06 04:28:36.789| fwdConnectStart: http://1link
2012/01/06 04:28:36.791| fwdConnectStart: got outgoing addr
192.168.102.100, tos 0
2012/01/06 04:28:36.791| fwdConnectStart: got TCP FD 13

so the main problem is that the request that comes from squid is not
using the right address in tproxy mode.

Thanks
