Description
Hello,
the purpose of my program is to collect all sent replies within 15 second of all devices in my network, after my SSDP-Discover via UPnP. Every 3 seconds, I send it again.
My program works on Windows XP, independent how many network cards are installed. In Windows 7 only, if only one network card is installed or active. This means, if all network cards are active, I get no UPnP-Responds. When I disable all network cards (vmware network adapter too!), except 1, my program works in Windows 7 too. the windows firewall is deactivated. no other security suite is installed.
The SSDPdiscover_V1 works as just described above. I use for UDPRecv the same port, which was used for sending.
In SSDPdiscover_V2 I've tried various UDPBinds to catch the incoming UPnP-packets, but nothing works :-(
I've just noticed with dismay, on Windows XP I receive only answers from devices, they are connected on the first network card.
I don't receive anything from the devices, they are connected on the second network cards.
When I want to "read" this devices, I must disable the first network card in Device Manager.
my friend told me, this must be a problem of the UDPOpen. In Java, there is the possibility to add the ip-address of the card, which should be used for the multicast. And I have to send the ssdp-request on each available network card and receive all the packets.
Code the the attached file.
But such a option is not available in UDPOpen. I don't know, where is the bug.
I try to discuss this problem in your and in the German forum, but nobody answered:

http://www.autoit.de/index.php?page=Thread&threadID=31882
it is independent on which computer I try this program. XP, Win 7, x64 or x32.
many thanks in advance
