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.

Cheers,

Paulo Matos
