4.0 Verify the eth0 interface is ‘up’
1.
Open-up a new Terminal window in the Linux box and verify the IP address and gateway.
Using the CLI, type:
#sudo ifconfig
password: ***** //Your user password is ‘patton’.
2.
Verify that the IP address, netmask, and gateway for eth0 is listed and the status is ‘up’.
3.
If eth0 is not listed or active, configure eth0. Bring up the ethernet configuration GUI by typing the ‘neat’
command:
#sudo neat
4.
Configure the IP address, subnet mask, and default gateway. Then, activate eth0 and save the configura-
tion.
5.0 Activate IP Forwarding
1.
Check if IP forwarding is activated using the following command:
#sudo sysctl net.ipv4.ip_forward
Or, you can also use the command below:
#sudo cat /proc/sys/net/ipv4/ip_forward
2.
If the resulting value is 0, IP forwarding is not activated. You will need to activate the service using the
following command:
#sudo sysctl -w net.ipv4.ip_forward=1
Or, you can also use the command below:
#sudo echo 1 > /proc/sys/net/ipv4/ip_forward
