Forward incoming UDP packets

[Prophet][]

I'm trying to find a simple way take an incoming video stream over UDP and forward it onto another ip address. I don't want to decode the video or view it for anything. I just want a program that accepts the packets and passes them onto another computer on different port. Effectivly a router I guess.

So far I have been using the System.Net.Sockets to try the following code

Declerations:

        

    Public receivingUdpClient As UdpClient
    Public RemoteIpEndPoint As New System.Net.IPEndPoint(System.Net.IPAddress.Any, 0)
    Dim udpClient As New UdpClient
    Dim OutputIP As System.Net.IPAddress = System.Net.IPAddress.Parse("127.0.0.1")
    Dim OutputPort As Integer = 1250
    Dim InputPort As Integer = 1234

Sub:

     udpClient.Connect(OutputIP, OutputPort)
     receivingUdpClient = New System.Net.Sockets.UdpClient(InputPort)
     udpClient.Send(receivingUdpClient.Receive(RemoteIpEndPoint), 0)

I am aware I'm sending it onto the same computer, I'm only doing it for now for testing purposes. I know this will need to run in a separate thread so that the program doesn't hang waiting for it to finish (which it never will)

I'm being a bit ambishous puting the receive code into the send method. What would be the best way to do this? Use 2 threads, one for receive and one for send? Save it to a buffer?

Any help would be awsome as network stuff is not my thing.

In the send call, you're specifying 0 as the second argument, when it should be the number of bytes you want to send. What you'd need to do is something like this:

Dim dgram() As Bytes = receivingUdpClient.Receive(RemoteIpEndPoint)
udpClient.Send(dgram, dgram.Length)

Use 1 thread for both the reading and the writing, cant see any advantage to use 2 threads in this case.

Ah, the answers are always so simple.

Cheers, that worked perfectly.
