IP forwarding enabled at startup?

[Shadrack]

I can't seem to get IP forwarding to turn on by default at startup.

I've altered the kernel config in: /etc/sysctl.conf

and changed:

net.ipv4.ip_forward = 1

I've also added the following line in: /etc/sysconfig/network

FORWARD_IPV4=true

Which is what pages on the internet seem to suggest I do. But when I reboot and do a:

cat /proc/sys/net/ipv4/ip_forward

i get a big fat "0" returned.

If I do

echo 1 > /proc/sys/net/ipv4/ip_forward

it will enable it for the session. I'm unfamiliar with what is automatically executed at startup. Is there anywhere I can just add the "echo 1 > /proc/sys/net/ipv4/ip_forward" so that on reboot it does that? What about just setting up the config file correctly to begin with? I'm in Fedora Core 3.

Thanks for you time and input!

You could add it to the network startup script. I'm unfamiliar with the FC3 init scripts, so you'll have to either find it or wait for someone. But it's as simple as adding that line.

If you plan on modifying the default initscripts, make sure that you create a backup of it first.

I'm not too familiar with FC3, but I'd suggest that you append the echo statement to rc.local (or similar.)

Look at /etc/sysctl.conf

# Disables packet forwarding
#net.ipv4.ip_forward = 0

change it to a 1 and uncomment it

then restart your network

I don't use Fedora but I remember a long time ago when I was using Redhat 9 I had to use this file. It is the same for gentoo.

correct me if I am wrong

**** Whoops, I am sorry I didn't see that you already tried that.... sorry... **** mods delete this post please

I would do what sentio says and append it to your rc.local
