Hello all,
I'm having a strange problem. I've set up an "access point" using hostapd, a wifi adapter (ral0), a wired ethernet adapter (mvgbe0 in my dockstar) and I bridged ral0 and mvgbe0 together using brconfig.
It works fine if I'm on netbsd-6. Specifically, 6.1_STABLE from kernels I've been building recently from netbsd-6. The userland is probably 6 months old or so.
However, on my dockstar machine with netbsd-7 and an identical setup, everything works fine EXCEPT wifi clients attached to wifi adapter ural0 (new name for ral0 in netbsd-7) or athn0 (another wifi adapter, not supported in netbsd-6) cannot get a DHCP address. If you google "hostapd dhcp not working", you'll see similar problem descriptions (but on Linux). If I set a static address on the wifi client, the problem is "solved".
This same dhcpd (installed on another machine in the same subnet) is working fine for many clients that are wired or attached to another wifi access point in the network.
