Network stack setup

[krystof@ibse.cz]

Hello everyone,
I have a question about network stack configuration in Linux. Lets assume a Linux host with multiple network interfaces, a different ip address is set on each interface (for example eth0: 192.168.0.1/24 and eth1: 192.168.1.1/24) and forwarding is disabled. When another host in the network 192.168.0.0/24 sets a default route to this host and ping to 192.168.1.1, it will get a reply. Is there any way to prevent this behavior - meaning the first host replies only to traffic with destination address set on input interface and not all addresses set on the host? Something like rp_filter but for destination addresses? Or is the only way to set up a firewall with input interfaces and destination addresses in every rule?

Best regards,
