How do I get the external IP Address of a NAT using the windows library? I am trying to find any information on INATExternalIPAddressCallback, but have only found one example in C++ using unavailable interfaces to C#. Any guidance would be much appreciated. -Karl Sorry, that I don't answer with an existing API from Windows that uses the UPNP service, but it migh help you You could also use a STUN-server on the internet, there are many open ones, every VOIP provider has one. http://en.wikipedia.org/wiki/STUN http://tools.ietf.org/html/rfc3489 e.g. open an UDP-socket, connect to stun.gmx.net on

My question is about "automatic discovery of file server service on local network". I want to implement a service which is file server basically and publish it on local network. Client PC which is connected to local network should find this service automatically and map (mount) network drive without user's intervention. As I look through web shortly, I think "Bonjour" for Apple and "UPnP" for Windows is best option to implement this kind of feature. Is this right assumption? Do you know any other good suggestion? How about Linux? UPDATE: FYI - I finished my zero-configuration SW implementation

I try to make a P2P Program and need help with getting through the NAT of the clients. I have read many questions here on stackoverflow, but i never got what the drawbacks and benefits of all the Methods to get through a NAT are. How many routers support which methods? Which methods are commonly used by the big companies? (BitTorrent, TeamViewer,...) What are the drawbacks/benefits of the three methods i listed and which else exists? UPnP requires software support in your router. Even when routers have it, it's sometimes turned off due to security concerns. STUN uses a simple public server to

I have done a bit of reading, and although I'm new to iPhone networking I was wondering if a TCP hole punch is possible for connecting two iPhones through NAT. I also read some helpful things about uPnP and hairpinning but I'm not to familiar with those at all, so if anyone has any ideas as to whether or not this is possible. My goal is to be able to connect multiple iPhones over a large range (so it may be better to switch to some type of GPSR) but for now I'm only working with two iPhones and 3G NAT Traversal seems the simplest and most reliable in theory. nat traversal is generic term used

I am searching for an open-source implementation of an UPnP client in Python, and more specifically of its Internet Gateway Device (IGD) part. For now, I have only been able to find UPnP Media Server implementations, in projects such as PyMediaServer , PyMedS , BRisa or Coherence . I am sure I could use those code bases as a start, but the Media Server part will introduce unneeded complexity. So can you recommend a client UPnP (and hopefully IGD) Python library? An alternative would be to dispatch calls to a C library such as MiniUPnP , but I would much prefer a pure Python implementation.

I'm using the default Visual studio UPnP library("UPnP 1.0 type library (control point)"). I list all rendering devices using UPNPDeviceFinder.FindByType. All works fine... Now I get the AVTransport service using the function: public UPnPService GetAVTransport(UPnPDevice mediaDevice) { foreach (UPnPService service in mediaDevice.Services) { Debug.Print(service.ServiceTypeIdentifier); if (service.ServiceTypeIdentifier == "urn:schemas

I can receive the UPnP NOTIFY Messages from UPnP Devices in my Network. But when i send the M-SEARCH Message, i get no Answers. I have tested the same code on a iOS environment (Monotouch for iOS, running on a iPhone simulator on a Mac). There it runs fine and i get all the search responses from my UPnP devices. I can also see the M-SEARCH message from my windows program. It looks like Windows (or a Firewall?) is hiding the
