first: Thanks for such an amazing OS like OpenWrt and a great community .I am pretty new on OpenWrt and sadly couldnt find any solution for my issue. I desperately try to configure a bridget AP. I do have a (non OpenWrt) base station connected to the internet and serving 2.4 and 5Ghz Wifi access (with DHCP enabled) to any LAN/WIFI clients. This works fine. No issue on that end. On the other end i do have a WL-755 dual band wall-plug wireless router/range extender with a 2.4 and 5Ghz radio + two 100Mbps Ethernet ports. The device had its own OEM firmware, but i flashed the box with the latest OpenWrt (OpenWrt 21.02.1 r16325-88151b8303 / LuCI openwrt-21.02 branch git-21.327.65561-7f37a58) and managed to connect to the base station on the 5Ghz band. Both Ethernet ports (LAN and other is named as LAN/WAN ports on the device surface) are attached as bridge ports to the br-lan device and are served from the LAN interface (attached to br-lan) with DHCP (own subnet, differs from the base station!). The entire box successfully connects to the base station. Both Ethernet ports will be served successfully with their own IP addresses (from the OpenWrt LAN interface) and can access the internet over the 5Ghz radio device. Works fine so far. The IPv6 stuff has been disabled on the box, since i do run a IPv6 network only (service provider end excluded here). Also the OpenWrt WAN and WAN6 interfaces have been deleted. I dont have any use for them.
So here comes the question: How do i make the box act as an Bridget AP to the base station, so the clients will actually get an IP address from the wired host router via WIFI and not the OpenWrt LAN interface? One important reason for this is broadcast traffic. It should work on a LAN network in Bridget AP mode. The current configuration connects via 5Ghz to the base station. The 5Ghz (wlan1 device) runs on a DHCP client interface and gets its own IP from the base station. Thats fine so far. But all wired clients attached to the Ethernet ports will get the different subnet IP address from the OpenWrt LAN interface (br-lan with attached ath0.1 and eth0.2). Anything connected to the Ethernet ports should get their IPs from the base station and should be able to communicate directly to the base. There is only a LAN (br-lan) and WWAN (wlan1) interface left. Config files will be attached later.
I found this tutorial, but didnt manage to adapt it on my configuration.
Pretty sure its kinda easy, but i really didnt manage to make it work. The only thing that i managed to do, is to lock my self out of the box with bad configurations and had to reset it countless. Thats really frustrating after some time. Here is what my current network and wireless config (without any Bridged AP config attempts) files look like:
config interface 'loopback' option device 'lo' option proto 'static' option ipaddr '127.0.0.1' option netmask '255.0.0.0' config globals 'globals' option ula_prefix 'fdc3:994c:e63f::/48' config device option name 'br-lan' option type 'bridge' option ipv6 '0' list ports 'eth0.1' list ports 'eth0.2' config interface 'lan' option device 'br-lan' option proto 'static' option ipaddr '192.168.3.1' option netmask '255.255.255.0' option ip6assign '60' config device option name 'eth0.2' option macaddr 'xx:xx:xx:xx:xx:xx' option ipv6 '0' config switch option name 'switch0' option reset '1' option enable_vlan '1' config switch_vlan option device 'switch0' option vlan '1' option ports '3 6t' config switch_vlan option device 'switch0' option vlan '2' option ports '4 6t' config interface 'wwan' option proto 'dhcp' option device 'wlan1' config device option name 'eth0' option ipv6 '0' config device option name 'eth0.1' option type '8021q' option ifname 'eth0' option vid '1' option ipv6 '0' config device option name 'wlan1' option ipv6 '0'

I really dont know how to adopt that tutorial mentioned above to my configuration files
Btw, device looks like this (EU and US versions slightly differ on case size and color):
Thanks for any help.
