Hello,
I am new to this mailing list sorry If I ask any thing
wrong.
My question is if I use REDIRECT action in PREROUTINg
rule is it going to change the tcp packet DST address.
If I lose original DST address, how can I persist that
value in that packet.
Help me !!!
Thanks in advance.
Nari.

Yes, it is changed to a local address i think (or loopback one). The
original address is restored after routing by NAT system to packets
which comes back (as source address).

I think you're looking for the SO_ORIGINAL_DST sockopt.
