Udp.remoteIP() always return 255.255.255.255 and Udp.remotePort() always return 0. If I set the IP and port manually instead everything works ok. My host pc has a windows 10 OS. I've also checked with wireshark that every ip and port is ok. Arduino code:
In UDP, the client does not form a connection with the server like in TCP and instead just sends a datagram. Similarly, the server need not accept a connection and just waits for datagrams to arrive. Datagrams upon arrival contain the address of sender which the server uses to send data to the correct client. 40G/50G UDP/IP Hardware Protocol Stack. Implements a UDP/IP hardware protocol stack that enables high-speed communication over a LAN or a point-to-point connection. Designed for standalone operation, the core is ideal for offloading the host processor from the demanding task of UDP/IP encapsulation and enables media streaming with speeds up to 50Gbps even in processor-less SoC designs. UDP scan works by sending a UDP packet to every targeted port. For most ports, this packet will be empty (no payload), but for a few of the more common ports a protocol-specific payload will be sent. Based on the response, or lack thereof, the port is assigned to one of four states, as shown in Table 5.3. User Datagram Protocol (UDP) is a Transport Layer protocol. UDP is a part of Internet Protocol suite, referred as UDP/IP suite. Unlike TCP, it is unreliable and connectionless protocol. So, there is no need to establish connection prior to data transfer. FreeRTOS+UDP is a small, fully thread aware, sockets based, and very efficient UDP/IP (IPv4) stack for FreeRTOS. It was created specifically for, and contains the features needed by, our new Internet of Things solution (currently being documented).

The uIP is an open-source implementation of the TCP/IP network protocol stack intended for use with tiny 8- and 16-bit microcontrollers. It was initially developed by Adam Dunkels of the "Networked Embedded Systems" group at the Swedish Institute of Computer Science, licensed under a BSD style license, and further developed by a wide group of developers. uIP can be very useful in embedded systems because it requires very small amounts of code and RAM. It has been ported to several platforms, inc Encapsulation of user data in the Unix -style UDP stack, in which each new layer includes the data from the previous layer, but without being able to identify which part of the data is the header or trailer from the previous layer. This effectively hides (encapsulates) the information from lower layers.
addition, the stack includes light-weight and high-performance implementations of the TCP and UDP transport layers, as well as other supporting modules such as IP, ICMP, DHCP, ARP, and DNS. Network Metrics
Implements a UDP/IP hardware protocol stack that enables high-speed communication over a LAN or a point-to-point connection. Designed for standalone operation, the core is ideal for offloading the host processor from the demanding task of UDP/IP encapsulation and enables media streaming with speeds up to 100Gbps even in processor-less SoC designs.
