Hello, Nikola Knezevic a écrit :
is it possible with iptables to redirect all the traffic to go to the network interface, instead of the loopback?
Note that the loopback /is/ a network interface. Do you mean a physical interface ?
I have two virtual interfaces, eth0:1 (10.0.0.1) and eth0:2 (10.0.0.5).
These are IP aliases, not virtual interfaces.
When a process sends a packet from 10.0.0.1 to 10.0.0.5, I would like to ship that packet to the gateway, which will return the packet back to this machine. Is this possible with iptables?
This is not possible with a standard kernel. Even though it may be possible thanks to some kernel patches (maybe the ROUTE hack from netfilter's patch-o-matic, use at your own risk), you would run into trouble when the packet is received back : the IP stack discards packets with a local source addresse received on a non-loopback interface.
Also, can I do the same thing now just for IP, but for ICMP?
Huh ? What do you mean ? -- To unsubscribe from this list: send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
