Yes of course, I´ll try it!
Main Router IP4 Adress: 192.168.0.1 on subnet 255.255.255.0 and DHCP range between 192.168.0.2 -192.168.0.161
In the Main Router I enabled the DMZ to the Basement Router.
Also i set Port forward 443 to the Basement Router OpenWrt.
And Static Route: Destination Network 192.168.2.0 with Subnet Mask 255.255.255.0 forward to the Basement Router OpenWrt (192.168.0.28) (!! But i think this doesn´t matter! Not sure!)
So far so good for the main router upstairs.
Downstair Router OpenWrt
I go to Interfaces/Lan and change Lan IPv4 adress to 10.0.0.1 and subnet mask to 255.255.255.0 and Interface-Lan Firewall to "lan"
I created a 5GHz WLAN by scanning and connect to my Main Router.
