Hi,
I tried with a second device (my iPhone):
root@OpenWrt:~# tcpdump -i wlan0 udp port 68
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on wlan0, link-type EN10MB (Ethernet), capture size 262144 bytes

at the beginning there's the camera MAC address, still trying to connect, and when I tried with the phone there's the new mac address.
The strange (to me) is that:
the two devices seems connected and with a good IP (in the case of the camera is even the one I set in the router, even if now I have the doubt that I set as static also when I configured the cam...) but, for example, my iPhone is still saying "no connection" and has 169.254.9.100 as IP...
Thanks,
Matteo
