i've a question i couldn't find a proper answer in the last days for. Hope someone can help me.

So there is this "console" which has a bunch of controls internal in its software. I like to control it out of a max patch to have a fast access, while performing through.

The "console" the patch should work with uses the source port for returning OSC over UDP as standard. This is not changeable. So it recognizes any new message as new client because of the different port which comes with it from max.

So, there is a need to use static ports when sending OSC messages over UDP to a remote console. Unfortunately UDPsend in Max and also the java external class 'net.udp.send' doesn't provide that.

Is there already a proper external or other object which would do the job i'm looking for?

static-udp-ports-for-sending-osc

do you mean static IP address? Because the port number will be the one you write in the object - for instance "[udpsend 169.254.0.2 8000]"

setting your own ip to static is doable, but that's an OS thing.

No, it's only about the port. The port number i write in the udpSend-object is only the port number of the destination, but not the source port. I've already checked this with WireShark and any udpsend, for instance "[udpsend 169.254.0.2 8000]", has a different source than destination port.

What i want is to declare a static outgoing port, which doesn't seem to be possible with native Max-Objects, as far as i know.

To give you some more background information why or what i'm actually analyzing:

I'm currently sending OSC respectively UDP messages over an Lemur interface, cause the Lemur does the job, i've described in my first post, very well. Every package i caught within WireShark has the same source/destination ports. Nevertheless the Lemur isn't the first choice anymore.

But because it works with the OSC-Communication perfectly i'm currently using it to analyze the difference to the network traffic which goes out of Max, cause i couldn't get the same results with Max till now.

Hey Wetterberg,
thanks for the quick response.

ah, wow. that sounds incredibly tricky. Yeah, I'm thinking you'd need some kind of spoofing software or something as a middleman.

have you made any progress as for defining a static source port for UDPing?

hei jan,
have you made any progress as for defining a static source port for UDPing?
i'm struggling with a similar situation.
