LXC running in DMZ

Hi all,
I would like to ask for help...
I need to create DMZ and also LXC (v. 4.0.12) container running in this DMZ. I just want to run some app in container, accessible from internet and keep rest of my home network safety.
I'm using TurrisOS 6.4 ( OpenWrt 21) / LuCI branch git-23.093.57360-e98243e

Thank you for help

Then you should ask Turris, it's their Openwrt derivative.

I did with no answer.
I believe there is a larger community here to find help with my answer

Sure, but those people have Openwrt knowledge.

Not as long as you run the Turris fw.

is LuCi or command line networking from Turris different than LuCi from OpenWRT? or LXC configuration?

Ask Turris, it's their fw, not ours.

OK,
how would you configure it in OpenWRT?

You start by installing proper Openwrt.

and what next?

This firmware is not provided by the official openwrt project. It was created by another party and is likely highly modified relative to the official version. As such, it is not supported here.

Please reach out to the maintainer of that firmware for help.
