      Hi,

      I am trying to send udp packet to my remote Server with at command at+nsocr and at+nsost.
      When I try sending udp packet to Echo Server like “85.214.66.173” or ping google DNS “8.8.8.8” it seem to works. But when i tried to send udp packet to my remote server there are no packet arrived.
      In my remote server, there are a programm names Node-red running and a UDP-node listen to a given port. I tested this udp node already. This node kann receive udp packet which ist sent from other Programm from other IP.
      Do I missed anything. Could somebody please tell me what is the problem?

      Regards,
      Linh
