Breakthrough, changed the ARGS to

DHCPDARGS=eth0

and it is working :)

 but now selinux gets in the way :(

How can I allow it to work?  


Thanks,

After this breakthrough I also found out or not sure here?
is that iptables are forwarding packets to eth1

upon reading another page:
http://chwang.blogspot.com/2007/11/making-linux-fedora-core-8-as-gateway.html

it says iptables and has this part:  

# Forward all packets from eth1 (internal network) to eth0 (the public internet)
iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT
# Forward packets that are part of existing and related connections from eth0 to eth1
iptables -A FORWARD -i eth0 -o eth1 -m state --state ESTABLISHED,RELATED -j ACCEPT
# Enable SNAT functionality on eth0. a.b.c.d are generally the ip of the eth0
iptables -A POSTROUTING -t nat -s 192.168.1.0/24 -o eth0 -j SNAT --to-source a.

Then it recommends visiting the other page which was referenced before.  

I will probably get to this machine tomorrow or on Monday.  I hope that I can get this working and with advice from the list I believe it can get done.

Regards,

Antonio
