So i have RB411AR:
wlan1 assigned to bridge1
metarouter (mr1) with bridge1
pppoe-client assigned to bridge1
metarouter (mr1) with ether1
dhcp server on ether 1
wlan 1 with a pppoe client
wlan 2 disabled
This setup allows me to have two pppoe-clients running on wlan1, one for the main rb411 and one for the customers metarouter.
Works great up untill the point i enable wlan2.
Once i enable wlan 2 and reboot the metarouter reports that it cannot create the pppoe interface.
