I added the following and saved them iptables-save


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.

I added everything here except last line "Enable SNAT", I do not know what that means, I know it is close.  I can ping the host machine, it gets an ip, it gets DNS, and all, but cannot surf :(

Thanks,

Antonio
