Explanation
"TFTP is a UDP-based protocol. Servers listen on port 69 for the initial client-to-server packet to establish the TFTP session, then use a port above 1023 for all further packets during that session. Clients use ports above 1023" https://docstore.mik.ua/orelly/networking_2ndEd/fire/ch17_02.htm Besides, Google Cloud external TCP/UDP Network Load Balancing (after this referred to as Network Load Balancing) is a regional, non-proxied load balancer. Network Load Balancing distributes traffic among virtual machine (VM) instances in the same region in a Virtual Private Cloud (VPC) network. A network load balancer directs TCP or UDP traffic across regional backends. https://cloud.google.com/files/gcp-mpaa-compliancemapping.pdf
