After PPP is UP, UDP packets not reaching the server IP.

Hi Guys,

I have been working on the PPP network between HL6528 to Server.

I had completed the upto IPCP protocol and got the dynamic IP for the device.

When i packs the UDP data with the source and Destination IP along with Port addresses, UDP packets not received in the Server IP.

I have checked in the Wireshark application in server end to monitor the receiving packets.

Kindly suggest us, how to verify the Send UDP packets and what is going wrong when sending the UDP packets to server.

could you please share your AT command sequence and how you are doing both PPP and UDP?


Hi rex,

Sorry for the delayed response.

Actually the problem was in Check sum of the UDP packets.

After putting correct check sum, Packets are receiving to server properly.

Thanks for your support.
