i have redhat enterprise linux5 server with many client PCs ..the clients include windows 7.How to share internet from the redhat linux server.it was urgent if u know ..pls help me.

"Share Internet" is a bit vague, you give no indication of your network topology with regard to how your network connects to the outside world.

What exactly are you trying to do?

hai TenTenths....i will tell in detail

1) my network is Ethernet with 100Mbps speed
2) i have an a modem with broadband connection...(with a static IP)
3)i have taken internet in Redhat 5 Linux machine, which I plan to make the server.
4) this server is connected with a switch.
5) the same switch has other clients, which include windows as well as linux computers.all are in WORKGROUP.

my doubt is that how to share internet from the Redhat Enterprise Linux 5.0 machine...just like we do ICS or NAT in Windows computer.

pls replay fast

just do a SNAT iptables rule ! the SNAT is just propper suit!

Here is one example howto:

You didn't indicate what type of server you are going to set up. If it offers services on the internet, its best to have it in a DMZ zone.

The rhel host will be the default gateway. You either need to configure a DHCP server (maybe on the RHEL server) or manually configure the LAN hosts with the value of the RHEL's LAN side IP address.

thank you so much......

dear friend I have another doubt.Is the Linux server is capable of providing IP to clients without setting static IP on them, just like what Windows ICS do? (without setting DHCP server in RHEL?)

anybody please answer my question

Hi Shinu051.
A Linux machine is capable of almost everything. Nearly yesterday I saw a news about robots been delivered with a built in Linux OS. Pretty cool hum?

OK, Let's go to your question: Can u deliver Dynamic IPs? Yes

There is a service(package) called DHCPD, that is responsible for assign IP to clients configured to dynamic IP.
Depending on your distro, it can be very easy to install it.

REDHAT alike(rpm packages): "yum install dhcpd"

DEBIAN alike(apt packages): "apt-get install dhcp3-server"


After you install the package, go and edit the file "/etc/dhcpd.conf"(redhat) or "/etc/dhcp3/dhcpd.conf(debian)" to suit your needs.

Hope it helps you.

thanks........
