It's because 2 or more gateways of mine could be accessible by the same interface. I have to distinguish the route on the base of the last hop, not on the base of the interface. If I get it right, the kernel is aware of what the MAC address of the previous hop was, but it is not aware of its IP address. This is surprising to me. I mean, I can understand that this information is not in the headings of the packet, but nevertheless I thought the kernel was able to remember the gateway it came from. If this is the situation I have to live in, then what are the commands I must give to instruct the kernel? Suppose I want a packet for 192.168.1.0/24 to be forwarded to 192.168.2.1 if the packet was sent to me by MAC 00:22:44:99:66:77.
