While trying to figure out the problem I noticed that tracing with tcpdump made it work again. The setup I have here is the following: PPC embedded board where the wired NIC and the wlan NIC are in a bridge. Dnsmasq is listening on the Bridge device itself. Looking at the changes between rc5 and rc6 I noticed commit bd4265fe365c0f3945d: bridge: Only flood unregistered groups to routers For testing purposes I reverted it and the cellphone immediately got an address even without running tcpdump. Now apparently the commit states that the user can always force flooding behaviour to any given port by marking it as a router but I did not find any documentation how to do that. Now my question? Is it "normal" that this change breaks my setup here and if it is expected how can I force my ports to the old behaviour without reverting the commit. Thank you very much in advance, Michael
