Routing packets via a C program

[<bedogniluca-linux@yahoo.it>]

Hi all
        i'm writing down a simple program for routing
the packets manually.
The idea is:
if a packet comes from a specific IP (192.168.0.2) I
set ip->saddr to my ip 
and then accept it. And, if a packets comes from the
outside, i set ip->daddr 
to 192.168.0.2 and then accept it.
I recalculate the checksum and it's correct (i can see
that by printing it out).

The basic problem is that, sniffing packets with
wireshark, i can see the 
packet from 192.168.0.2 to outside, but not mine to
outside.

I also tried with NF_REPEAT and NF_ACCEPT and NF_QUEUE
when calling 
ipq_set_verdict, but nothing changed..

Any hints? RTFM?

Regards
