Hi there,
I'm running openwrt under lxc container, used this image. But, when I'm applying / reloading firewall rules, it is not applying:
**fw3 reload**

And because of that no internet access. If try to run owrt in virtualbox or other VM, copy rules and paste in lxc container, it is applying and working. So, why firewall won't apply rules from /etc/config/firewall?
I asked you to edit the first post too. Hit the edit button and include the configuration in preformatted text. Thank you! Since you appended it in the second post, remove it from the first (or fix it anyway), as it is occupying too much space and is hard to read.
You have changed the default name of the interface from wan to Inet, but in the firewall configuration it still is wan.
I already edited the first post...
Anyway, it seems like firewall won't read config file, even with default config (like in the first post) it is not working.
This is a warning that firewall cannot find the wan and wan6 interfaces, which makes sense since you removed them. So you can remove them from the wan zone too.
Post also the following:

There are some more topics in the forum regarding networking with LXC container.
e.g [Solved] Networking for LXC container
I'll step down as I have not dealt with it.
Hey, found this script for build special image for lxc/lxd, now system working well ! I don't understand how this script patching system, but it works!
