Answer / anindian
1st answer is correct till you boot your Linux machine, once
rebooted, its gone coz the /proc is a fs that is resident on
memory, thus if you want to forward your packets permanently
then you have to alter the net.ipv4.ip_forward parameter to
reflect the changes each time machine is booted. # sysctl -p
makes it effective without reboot.
