NAT issue
Locked
 
|
Hi All,
I have written a streaming sever and client application using udpsrc and udpsink plugins respectively , where the server streams the data to the client over a perticular port. this works perfectly when both server and client are in the same LAN. But when the server and client are in a different LAN, with a server having a global ip and client with a local LAN ip i need to unblock the ports at the router for the streaming application to work. Is there a method which i can use, so that client works without unblocking the ports on the router? regards, Sumanth.V ------------------------------------------------------------------------------ The Palm PDK Hot Apps Program offers developers who use the Plug-In Development Kit to bring their C/C++ apps to Palm for a share of $1 Million in cash or HP Products.

HI,
Just out of curiosity why did you call this a NAT issue? It sounds more like a firewall issue. The only way that this could work without having to unblock ports is to use a port the you already know to be open. Is having the clients open up the ports really a problem. This is the whole idea behind firewalling. Block out everything except the ports that you need open but if you need a port you should be able to use it. If the people that are using your client are concerned that this would be a security risk just ensure them that your app does not have any whole (once you have made sure that this is true of course).

Look into Upnp or other Nat traversal solutions, there are lots of protocols with issues like this. Also you may want to look at using a tcp server/client instead of udp as once connected from the client, two way communication happens, whereas with udp maybe not?? ------------------------------------------------------------------------------ The Palm PDK Hot Apps Program offers developers who use the Plug-In Development Kit to bring their C/C++ apps to Palm for a share of $1 Million in cash or HP Products.

This was one of the reasons why we decide to use ZeroC's Ice middleware with appsrc/sink for our streaming purposes. They have pretty powerful solution for firewall related problems - http://www.zeroc.com/doc/Ice-3.4.1/manual/Glacier2.43.2.html. We will provide more details in our presentation at GStreamer conference.
