I have the AX3600 version from European distribution.
I went back to version 1.0.17 to enable ssh (I used the tutorial https://openwrt.org/inbox/toh/xiaomi/xiaomi_ax3600) then uploaded @ alllexx88 https://www112.zippyshare.com/v/9Z0MFiYm/file.html using https://github.com/geekman/xqrepack#usage.
Everything worked out, I have version 3.0.22 (in English) with working SSH access, I turned off dns in dnsmasq to use the better smartdns software - it worked 
I have a problem with "Activate NAT reflection for this redirect - applicable to DNAT targets.", I have redirected ports for openmediavault. I can access the domain from the external network and only via wifi on the internal network, access from the equipment connected via the cable does not work.
Do you know how to fix it?
