domain-name-servers should be IP addresses. Which to
use I can't judge,
but maybe the 2 of your ISP may be best choice.

Make sure you have forwarding set on on the gateway
host:
$ cat /proc/sys/net/ipv4/ip_forward
must print out "1" (without quotes). If it does not,
then activate it in
/etc/sysctl.conf and run "sysctl -p". Make too sure
the gateway does NAT
by an iptables rule like:
iptables -A POSTROUTING -o eth0 -j MASQUERADE
[eth0 should be in your case the outgoing device]
eth0 is the incoming connection should eth1 be the
outgoing. I'm a little confused but getting there.

I have made most changes that Jeff and Alexander have
provided and I know that I am close as possible to
getting this thing going.
I tried to connect to the internet from within Windows
98 machine and I get a DNS error and cannot connect.
However, the ipconfig /all, ipconfig /release_all and
ipconfig /renew_all give the following
iprelease gives

It is probably something with the settings.
Apparently everything looks ok but connection not
good. Thanks for all suggestions and help provided.
Kind Regards,
Antonio
