Hello. I would like to receive UDP packets which are send in TCP
network by some machine (I looked packeta by using Etherreal so I know
all essential informations). This machine send them from its IP to
255.255.255.255 . Is there exist the way in which I could receive them
? I'm using TidUDPServer and its events IdUDPServer1UDPRead which offer
record called ABinding. But when I write somethins like that :

procedure TForm1.IdUDPServer1UDPRead(Sender: TObject; AData: TBytes;
ABinding: TIdSocketHandle);
begin

label1.caption:=ABinding.PeerPort ;
label2.caption:=ABinding.PeerIP;
end;

and it is preceded by

IdUDPServer1.Active:=True;
IdUDPServer1.BroadCastEnabled:=True;

I don't receeive anything. In additional procedure onRead is not
working at all. What am I doing wrong ? I've written two applications
recently ( by using UDPServer and UDPClient) - one of them send UDP
packet whilst the other read it without too much difficulty - in
exactly the same way as do it now...
