Subject: RE: Re-routing packets via netfilter (ip_rt_bug)
Date: Mon, 25 Apr 2005 18:51:25 +0200	[thread overview]
Message-ID: <4151C0F9B9C25C47B3328922A6297A3286CFA5@post.arx.com> (raw)

No, this does not help.
The failure is now inside "ip_route_output_slow", since the reversed address packet has the source address of the remote machine, and the call to "ip_dev_find" fails to find a device with matching address.

In 2.4 the okfn pointer used to point to "ip_queue_xmit2" which evaluated the new route from scratch. 
It was passed in as the completion function when calling the NF_HOOK chain.
In 2.6 this function is gone (replaced with a reference to "dst_output).

Was removing it a mistake?

Does this patch fix your problem?
