Thanks for your answer.

As soon as receiving your reply, I tried those and results are below.

OS version : linux-2.6.12.6 with cttproxy-2.6.10-2.0.1.tar.gz

    test                   status

========================================================

bridging - on           (not working)

bridging - off          (not working)

using TPROXY rule

instead of REDIRECT     (not working, halting system)

REDIRECT Rule without Bridging :

    iptables -t nat -A PREROUTING -i eth1 -d 192.168.0.107 -p tcp --dport 9999 -j REDIRECT --to-port 9216 TPROXY target Rule :

    iptables -m physdev -t tproxy -A PREROUTING --physdev-in eth1 -d A.B.C.D tcp --dport 80 -j TPROXY --on-port 2101

My poor daemon couldn't read any data in any contditions.  )-;
