Atv and iptables and OpenVPN

Team, I have installed the latest OSMC on my appletv 1st gen but when I try using iptables it shows such error:

root@osmc:/home/osmc# iptables --list
modprobe: FATAL: Module ip_tables not found.
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.

There is no ip_tables module.

I downloaded the kernel sources and compiled new kernel with the netfiler options, but when I try installing it, I see that /boot is ro, the mount in rw does not work. Obviously, I miss something. Any help on what am I doing wring is highly appreciated:

HFS+ will mount as read only if it is uncleanly unmounted.

So you need to run a forced fsck on /boot while it is unmounted or mounted read only, then you should be able to remount it read write.

Thanks, this did work. fsck.hfsplus did not find any error though, but I was able to mount it rw. Will keep trying.

Still no luck yet with the iptables. New kernel is used:

Linux osmc 4.2.3 #1 Sun Feb 28 00:21:25 EET 2016 i686 GNU/Linux

I did insmod two modules:

But iptables still does not work:

root@osmc:/lib/modules/4.2.3/kernel/net/netfilter# iptables --list
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.

Really, I am trying to setup an OpenVPN (works) and set up routing. The OpenVPN is setup on ATV box that is a different unit from a router. All sources that I read about this require ip forwarding to be done using iptables.

It doesn’t matter if it finds an error or not.
If the HFS+ boot partition is not cleanly unmounted, it won’t mount read/write until it has been checked to make sure it ok. This is normal behaviour with HFS+ on Linux.

I can’t advise on iptables though…
