Hi all

I must instruct my server to route packets based on destination prefix
and on the gateway from which the packet arrived.
E.g.
 I am 192.168.0.1
 a packet for 192.168.1.0/24 which arrived from gateway 192.168.0.2
must go through 192.168.1.1 dev eth0
 a packet for 192.168.1.0/24 which arrived from gateway 192.168.0.3
must go through 192.168.1.2 dev eth1
 a packet for 192.168.1.0/24 which arrived from any other gateway must
go through 192.168.1.3 dev eth2

The gateway I mean is just the last hop traversed, before me. It's not
necessarily the source of the packet.

How am I supposed to do that?

Regards.
