> stupid question: is IP forwarding enabled (sysctl > net.ipv4.ip_forward)? argh, last week there was a maintenance cycle in our datacenter and every machine was rebooted. I thought echo "1" > /proc/sys/net/ipv4/ip_forward would be persistant but I was wrong. Also I forgot to check if it was still there after the reboot. Really sorry, this is time lost! Thank you very much, good job! Régis
