how i can configure my server like router for control a network
lab to share one way to get out to internet. My server have 2 network cards. My server already get internet, but the other
computers in the lab not get the out to internet.

Hi,
First step is to activate packet forwarding in your kernel if it is not already set.
You can check the seeting by issuing the following from a consle as root or equiv.
cat /proc/sys/net/ipv4/ip_forward
If the value returned is 0 the forwading is disabled. To enable use sysctl -w
sysctl -w net.ipv4.ip_forward=1
or echo
echo 1 > /proc/sys/net/ipv4/ip_forward
To make this a permanent change (you will want to) change /etc/sysctl.conf.
Using an editor find the line
net.ipv4.ip_forward = 0 and change the 0 to a 1.
You can just change sysctl.conf then issue a systctl -p /etc/sysctl.conf to lad the config.
