There are many postings related dhcp with relayd problems in this forum, but not specific my problem.

My desired config:

propriatary Cable-Router(BlackBox) as IAD and DNS/DHCP-Server -> OpenWrt17.0.1-Router/Repeater with wlan-sta/wlan-ap/lan -> wired/wireless-clients

Networks:
lan = bridged eth* and (optional) wlan-ap
wwan = wlan-sta
relayd-bridge between lan wlan

without dhcp and static-client-ips everything works like a charm, with the wlan-ap down also even with dhcp, but with the wlan-ap up dhcp-requests are not forwarded, independent of the configuation of tha wlan-ap network, if it is in a seperate subnet, or if it is ip-configured at all

remarks: the wifi-section in networks is only for testing purposes to set up the wlan-ap as a discrete/nonbridged-network, but that makes no difference

tried it also with dhcp-fwd and dnsmasq -dchp-relay-option, but no success
with AP off, everythings perfekt AP-on, no dhcp

firewall is off

I'm really wondering what has the AP to do with dhcp, even if it's not tied to any related network or bridge
