I'm fairly new to Wireshark, but understand how to set filters etc.
I need to measure the comms traffic between two applications on a network, that communicate via UDP.
The problem is, with UDP, the packets obviously don't have destination IP addresses, so what kind of filter can I write?
I have considered installing the application on the receiving node, but for reasons I won't explain, this is not an option. I intend to use wireshark on a laptop plugged into to a spare port on a switch.
Can anyone advise on how I might achieve this?
