Masquerading does not work

Symptom:

You want to give internet access to other machines in your network using a linux host with IP masquerading functionality. However, even though the kernel options and the variables in /etc/rc.config seem to be correct, there's no connection.

Cause:

Eventually, ip_forwarding is installed in the linux kernel, but has not been activated yet.

Solution:

Set the variable IP_FORWARD in /etc/rc.config to "yes". Forwarding will be activated after the next reboot. If rebooting is not an option, you can activate the forwarding functionality by hand:

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