Just a quick question ( I Hope ) To find out if what I'm trying is even possible. I am trying to share internet connection with Fedora12 as default gateway and XP machine hooked up via NIC using iptables commands as shown in Mark Sobell's book 'A Practical Guide To Fedora And Red Hat Enterprise Linux' These are the commands as placed in /etc/rc.local

iptables -A FORWARD -i eth1 -o eth0 -m state --state ESTABLISHED,RELATED -j ACCEPT

iptables -A FORWARD -i eth0 -o eth1 -j ACCEPT

iptables -A FORWARD -j LOG

iptables -t NAT  -A POSTROUTING  -o eth1  -j MASQUERADE

I did flip the in and out parameters to match my NIC configuration ( as opposed to example from book ) but other than that followed example. One thing to note is that Sobell did not mention whether this should work with mix of Linux and XP. One other note ( maybe meaningless ) is that I do have samba working between the two machines. Thanks for any insights anyone might have. PL
