No, at least not using some kind of UDP socket or pcb. Instead, you could use a
raw socket which gets all ip packets for a specific IP and/or protocol.
However, doing this with the socket API is VERY unperformant as every incoming
packet is copied into your socket thread. Instead, you could use a raw-API raw
pcb, which does the same, but is zero-copy. However, With a raw socket/pcb, you
will have to do the protocol header parsing yourself...
