Connecting to internet through ethernet card..

Hi all,
Im new to Lnux... But i've heard a lot of about its flexibility, and
desided to change our gateaway's OS (from XP to Linux). I've choose the
Red Hat 9.0 distributive to operate with. From the first sight it appear
to me as friendly, easy to tune. But next things have kick me down... Till
now we where connected to Internet through ethernet card, we have the
fixed IP assigned by our ISP, we also have the ISP's DNS servers and
gateway. There is two ethernet cards on computer - one for Inet, another
one to distribute Inet traffic among local mashines. I've tried to make
everything as it wrote in clever book...
1. I've used ifconfig command to assign certain IPs and netmasks to
ethernet cards.
2. I've used route to add the default gateway.
3. I've turned firewall off AT ALL.
But I still can't even ping my ISP's gateway IP - all packets are sending
but nothing is received - 100% lost. In local network Is there any
additional things i should know. Whats wrong? I where installed the OS
whith most common setup. HELP!!!! PLEASE. I've spent about whole week to
get success - but nothing work out.

Did you turn ipforwarding on ?

Yes, echo "1" > /proc/sys/net/ipv4/ip_forward

From your story its not completly clear from which machine you cant ping.
Cant you ping from your Linux machine you installing now or from your
machines on the local network ? If you cant ping from the machines on the
local network ,how do they get an ip and default gateway ?

Did you set up a default route?

Describe your setup in detail - post output of

/sbin/ifconfig
/sbin/route

Are you trying to do NAT? Or does each of your internal machines have its
public IP address?

Let's forget about local mashines. let's forget about about second
(internal) network.
There is only Linux mashine connected (i try to do this) to ISP.

I think you missed something during the installation.

the parameters you apply with ifconfig are gone after reboot. Just use the
distribution configuration tools for that purpose.

If you are new to linux, do not do so complicated things with RH 9.0. This
is not a server OS, though you can still manage it. Because it is linux.

I think you have to try SuSE 9.0 or 9.1 for that stuff. It is more
friendly as for the beginners and you can install it via FTP-mirror or by
getting ISO's from the inet.

the install and tune tools in SuSE are easy to use and to understand.

I would suggest you look through the 'how-to's' which are probably
installed on your computer or which can be found at www.tldp.org. The
network howto should help you get things working.

Hi Alex,
just that I get this right: Redhat is not a server OS, but
Suse is? Very keen opinion, I guess ))

Hi Roman,
as you have been told, post the output of
ifconfig,
route and
iptables -L.
