I am trying to run a script which invokes iptables (it’s a VPN kill switch). When the script runs it spits out nothing but error messages. Typical is this:
**#** iptables -F
iptables v1.4.21: can't initialize iptables table `filter': Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
The modules “iptables” and “x_tables” are loaded. What other modules might I need to get this to work?
Have you updated your kernel but haven’t rebooted?
uname -r
vs
rpm -q kernel-default
What other modules are loaded?
My openSUSE box has quite a few, including iptables_filter:

Good luck.
