Hello, Andy Simpkins a écrit :
eth0 and eth1 will therefore share the same subnet.
Preferably not if you want to avoid trouble and dirty hacks.
How do I configure my firewall/router to route to these boxes correctly?
If you want the same subnet on two interface, you'd better bridge them together. You can filter bridged traffic using ebtables or {ip,ip6,arp}tables through the bridge-nf infrastructure.
