Enable Packet Forwarding

Question

I am using Fedora 20 after running this command:

"sysctl -w net.inet.ip.forwarding=1"

it is giving this error:

"sysctl: cannot stat /proc/sys/net/inet/ip/forwarding: No such file or directory"

I think you have to type:

sysctl -w net.ipv4.ip_forward=1

This works on fedora 21 for me

what for this sysctl -w net.inet.ip.fw.enable=1 – techboyz Sep 17 '14 at 06:26
Could you perhaps explain why this would help. especially since you are trying to write to the /proc filesystem, which is usually offlimits in *nix – Niels Bech Nielsen Sep 17 '14 at 06:50

su -      # sudo su - if Ubuntu
echo "net.ipv4.ip_forward = 1" >> /etc/sysctl.conf
sysctl -p /etc/sysctl.conf

This way even when you reboot the machine the setting will stay.

For Ubuntu:

sudo sysctl net.ipv4.conf.all.forwarding=1
echo "net.ipv4.conf.all.forwarding=1" | sudo tee -a /etc/sysctl.conf
