@marten-seemann But @mirjak makes a valid point. The sender may be unaware. It could be a case of a NAT rebinding (new outgoing UDP port) or you are on a WiFi spot provided by a cell-connected router that just migrated to a different operator.

Trying to confuse the network, you are confusing the server as well (unless your server is a single lonely box on a rack somewhere). CDNs are complex networks with multiple machines coordinating to present you with a nice "server" abstraction. If you are successful in confusing the network, you will confuse CDNs and as a result end users will get suboptimal performance and reliability for their connections.
