I need to be able to send a packet destined for the loopback address (i.e. 127.10.10.1 or some such address) out onto the wire. (eth0, eth1 whatever)
I have seen some documentation on a packet path with the old 2.4 kernel but the 2.6 kernel is completely different.
Can anyone point me to documentation on this? Or if not point me to the function that would best be "hacked" to get this to work.
My guess is I will have two places to hack:
1. Somewhere in ip_output.c
2. Somewhere in arp.c
thanks in advance.

Can't you just write an iptables module to register on the output chain, clone any skbs you intercept bound for loopback, and modify the clone skb->dev to point to the dev you would like to send it out?
