UDP Ports 67 and 68 are to do with DHCP
UDP Port 138 deals with Netbios over IP (Microsoft)
You need to be careful when you do port scans and make sure you're on the same network as the router. Where did you perform your scan in relation to your router? This *may* be a false representation from your port scanner.
