UDP is a connectionless protocol, so I would not expect to ever find any UDP "connections" in state 1. If the router in question is running NAT, it does need to keep track of UDP flows in order to match incoming UDP packets from the Internet with the previously-transmitted UDP packet(s) which elicited the response. The router needs to do this so that it will know which of your internal IP'd hosts it should send the packets to. Since UDP is connectionless, the NAT router has no way to know whether any further UDP packets will be forthcoming in a given UDP flow, which is why routers generally expire UDP flows from their NAT tables based on time-of-inactivity, or upon the table approaching or becoming full.
