Masquerading does not work
Support knowledgebase (grimmer_msq)
Applies to
SuSE Linux: Versions up to (including) 7.3
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
