11.5. Turning on Packet Forwarding
In order for the LVS router to forward network packets properly to the
real servers, each LVS router node must have IP forwarding turned on in
the kernel. Log in as root and change the line which reads
net.ipv4.ip_forward = 0 in
/etc/sysctl.conf to the following:
The changes take effect when you reboot the system.
To check if IP forwarding is turned on, issue the following command as
root:
/sbin/sysctl net.ipv4.ip_forward |
If the above command returns a 1, then
IP forwarding is enabled. If it returns a
0, then you can turn it on manually
using the following command:
/sbin/sysctl -w net.ipv4.ip_forward=1 |
