Hi, I'm using OpenWrt 23.05with nearly default configuration.
This means that wan interface receives a dhcp-IP from the upstream-router (= Firtzbox).
The upstream-router transmits an SSID.
I want that the same SSID is also transmitted by OpenWrt. Clients conneting to this OpenWrt-SSID should receive IPs from upstream-DHCP and traffic should be routed directly to the upstream-gateway (via WAN-RJ45-connection, there is no Wifi-bridging between both APs).
So I configured a SSID on OpenWrt in Access Point Mode with the same name and PSK as on the upstream router. This SSID is associated with interface WAN.
I can connect to this OpenWrt-SSID, but don't receive an IP from upstream DHCP.
The main functions of OpenWrt within default-config, e.g. acting as a router+firewall must stay in place on my OpenWrt. I "just" want the addon of transmitting the SSID of my upstream-router also on my OpenWrt-device.
I know this documentation, which adds WAN to br-lan.
I cannot to this because this otherwise a would loose my routing functionality.
I was not able to transfer this documentation to my specific situation.
Can you explain why you need two subnets, i.e. the routing/firewalling functionality of OpenWrt?
I don't see the point when clients can simply connect to the upstream AP instead.
wan-and wan6-interface from device WAN to br-lan.22
network of the desired SSID stays on wan-interface => now the SSID works because it uses a bridge-device
I use this config because I want to spread some VLANs over WAN to my fritzbox. The fritzbox-integrated switch is capable to transport tagged packages although you cannot configure VLANs on fritzbox.
My firewall-rules still keep the wan and lan zone separated.
Does anybody of you have security concerns because I joined lan ports and wan on the same bridge device?
