Hi, You're right. The problem was the iptables configuration. I've done: iptables -F iptables -X Then to share internet with my clients I've done: iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE however, it seems that it is not working, eth0 is my net connection. This should work, right? Maybe I'm doing something wrong in my clients config.
