Allow the network address to be specified for TCP and UDP writes (especially UDP multicast)

[banksey255]

Allow the network address to be specified when performing TCP and UDP writes in LabVIEW. 

For example, universal plug and play uses multicast messages for discovery. However, the multicast vi only transmits on the default network address. This makes multicast discovery impossible when I have multiple UPnP devices on multiple networks (I have multiple network interface cards and additionally use a VPN that acts as a virtual network adapter).

Can you provide VIs that demonstrate the issue? I don't know enough about networking to understand the problem so I'm not sure who to route this to. Is it a problem with the primitives, with how our network layer operates?

You can create PNGs of code to post here by selecting the code that shows the problem and choosing "Edit >> Create VI Snippet From Selection".

Not really sure what this is about. UDP write has a network address input to specify where the target address should be, and TCP is a connected sessions where the target address is defined at connection time and can't simply be changed afterwards.
