Receive UDP Broadcast when opening UDP port on specific IP

I can't receive UDP Broadcast when I open UDP port on a specific IP.
If I open it without specific IP or open the x.x.x.255 IP I do receive the UDP broadcast.
If I open the x.x.x.255 IP or without specific IP, only one erlang-instance per computer can listen to the UDP broadcast so that's no solution.

Can't receive UDP broadcast:
gen_udp:open(123, [{ip, {123.123.123.123}}]).

Can receive UDP broadcast:
gen_udp:open(123, []).
gen_udp_open(123, [{ip, {123.123.123.255}]).
