I'm trying to get a re-write rule to occur after routing has occured.
My host has the address 192.168.10.1 and a gateway of 192.168.10.2 to 192.168.11.0/24.


Sorry, but this can be possible. The gw for a network class must be
inside the _same_ class!

The re-write rule I have is:

# Map 11 net to 10 net iptables -t nat -A OUTPUT -d 192.168.11.0/24 -j NETMAP --to 192.168.10.0/24

It does the re-write but, as far as I can tell, isn't using the default gateway to 192.168.11.0/24.

I assume a POSTROUTING rule might do this, but when I use the POSTROUTING queue, it doesn't do the translation. Using mangle or DNAT produce an error, not surprisingly.

Is there any way to do this ?


Where the packet starts? If you use nat + output you are saying to the
kernel to do a thing when a packet are generated locally.
Are you the gateway for another network (lan)?
However, It's not so well explained what you want to achieve.
