Olsr and Netfilter

[Jørn Andre]

Hi!

I'm a newbie on kernel programming and on NETFILTER and in the middle of
making a netfilter-hook into PREROUTING and INPUT that simply changes 
the destination
of a packet. From the source-code I've read from Rusty Russel
and Harald Welte guide I can not see any difficulties with doing this, 
but in case
I'm wrong and before I try to break my kernel open....is it not 
possibly  to hook
in and change the destination of a packet  and then push it on without 
further notice?

I'm making a plugin for the Unik Olsrd implementation which is supposed 
to eliminate
the gateway-problem it has. By changing the destination in INPUT  at the 
source-host and then
change it back to the original in PREROUTING at the gateway I can 
preserve the route
and avoid a reset when the protocol changes default gateway because of 
topology changes.
