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.
