We were testing PONK connectivity over WLAN between two computers from Modulaser into the default TouchDesigner receiver included in the repo and weren't able to get things working until I hard-coded the UDP socket to bind to my wifi interface. This is because on windows, wifi almost never has the correct metrics to be selected first when using
INADDR_ANY, which means our multicast messages don't get delivered.These changes switch to allowing both the sender and receiver to select a specific interface, falling back to default
INADDR_ANYbehavior. This mirrors other Touch UDP operators (e.g. Osc In/Out).I've tested this locally via multiple interfaces but haven't validated computer to computer for sure but things seem to work as expected.
