I have IP_FORWARD="yes"

and I can reach from the server through each Interface the Internet and the LAN machines. However the LAN machines cannot go out to the Internet.

I have restarted the network and the /var/log/messages says to that:

What do I miss?



How do you connect to the internet? It looks like you are using a public
address on eth1 which I am not sure is appropriate. I would expect a
ppp0 or adsl0(?) interface which connects to the internet through your
ISP.


The public IP is correct. The machine is really on the "wild Internet"
