Subject: Routing packets via a C program
Date: Mon, 22 Jan 2007 09:58:51 +0100 [thread overview]
Message-ID: <200701220958.51794.bedogniluca-linux@yahoo.it> (raw)
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 out
it).
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
