Hi,
just reporting, not sure it's for bug report or rather for discussion, are these errors OK ?

Sat Dec 17 09:01:00 2016 user.notice : Perhaps iptables or your kernel needs to be upgraded.

Thank you

I have same problem on Archer C50, just revert back to stock firmware, flash newest stock firmware using stock gui and then flash lede. It works for me.

Thank you, but I think I got this just with the most recent version.
So you are 100% sure it has disappeared after full reset, stock revert and re-flash ? Hmmm....

Same issue here on a wrt1900acv1 "mamba"
Tried the insmod to see if anything changed no go.
root@LEDE:~# insmod /usr/sbin/iptables (It does exist here)
failed to insert /usr/sbin/iptables

iptables v1.4.21: can't initialize iptables table `raw': Table does not exist (do you need to insmod?)

"raw" table was split off from the default config a week ago. That error message is likely due to that change: https://git.lede-project.org/?p=source.git;a=commit;h=970dd4dd58c1f1c1b4cde69a732483aacdc0236a

I have not noticed any harm from that, but apparently some (iptables/firewall) component still expects to find that table.

I filed a bug report. Let's see if devs respond somehow:

This iptables error is coming from LuCI iptables parsing code. The error gets triggered e.g. by visiting the Firewall status page in LuCI, and it also gets triggered by the LuCI Statistics module's config generation during boot time.

Discussion in FS#342

EDIT: And it should now be fixed with https://github.com/openwrt/luci/commit/b56d1a85e2fa2ba50b2253e07e41b421a2c20fca

does this means not having the raw table is normal, and have no harm?

Yes. It was removed intentionally.
