You can only connect to a router port if the router is running a service that Allows you to do so. What kind of connections are you trying to do? The net address is the ip address in u32. The port is determined by the service you want to access. What do you actually want to do with all this? We need much more info. Router model?

You are still not saying what sevice you are trying to acesss. Ther are not that many udp services (maybe SNMP?) available. Do you know the communication protocol? Is it a service that requires authentication?

If you simply want to receive syslog messages, just have the program listen on the syslog por and configure the router to send syslog to the ip address of the computer.

I need to comnunicate between two laptop so that I can send data  to and receive data from.

OK, that is something entirely different!

You should be able to use plain networking. The router is only relevant if it is running NAT and you are trying to connect from the WAN to the LAN side. In this case you need to forward the correct ports on the router due to the target ambiguity.

This is not related to LabVIEW, but basic networking.

Try this.
